Answers

Answer 1

The total number of possible outcomes, we get 3^8 - 2^8 = 6,305. Therefore, there are 6,305 possible outcomes in this scenario.

A, B, and C are the three up-and-comers in an eight-vote political decision. The winner will be the candidate with at least five votes and the absolute majority. How many outcomes are there if you take into account that no two of the eight voters can vote for more than one candidate and that each voter is unique? 3,8 minus 2,8 equals 6,305 less than 256.

This is because, out of the 38 possible outcomes, each of the eight voters has three choices: A, B, or C; However, it is necessary to subtract the instances in which one candidate does not receive the absolute majority. A candidate needs at least five votes to win the political race. Without this, there are two possible outcomes: 1. Situation: Each newcomer requires five votes. The newcomer with the highest number of votes will win in this situation. This applicant has three choices out of eight for selecting the four electors who will vote in their favor. The other applicant will win the vote of the remaining citizens.

This situation therefore has three possible outcomes out of the eight options available. An alternate situation: The third competitor receives no votes, while the other two applicants each receive four votes. There are eight unmistakable approaches to picking the four residents who will rule for the important candidate and four exceptional approaches to picking the four balloters who will rule for the resulting promising newcomer, as well as three decisions available to the contender who gets no votes.

Subsequently, this situation has three, eight, and four potential results. In 1536 of the results, one candidate does not receive the absolute majority: When this number is subtracted from the total number of results, we obtain 6,305. 3 * 8 choose 4) + 3 * 8 choose 4) + 4 choose 4) 38 - 28 = As a result, this scenario has 6,305 possible outcomes.

how is the variable manufacturing overhead efficiency variance calculated?

Answers

Variable Manufacturing Overhead Efficiency can be calculated by comparing the standard cost of actual production at the standard number of hours required to produce the actual output, which is multiplied by the standard variable overhead rate per hour, with the actual variable overhead cost incurred in producing the actual output.

Variance is calculated by comparing the standard cost of actual production at the standard number of hours required to produce the actual output, which is multiplied by the standard variable overhead rate per hour, with the actual variable overhead cost incurred in producing the actual output.

The following formula can be used to calculate the Variable Manufacturing Overhead Efficiency Variance:

Variable Manufacturing Overhead Efficiency

Variance = (Standard Hours for Actual Output x Standard Variable Overhead Rate) - Actual Variable Overhead Cost

Where,

Standard Hours for Actual Output = Standard time required to produce the actual output at the standard variable overhead rate per hour

Standard Variable Overhead Rate = Budgeted Variable Manufacturing Overhead / Budgeted Hours

Actual Variable Overhead Cost = Actual Hours x Actual Variable Overhead Rate

The above formula can also be represented as follows:

Variable Manufacturing Overhead Efficiency Variance = (Standard Hours for Actual Output - Actual Hours) x Standard Variable Overhead Rate

Therefore, the Variable Manufacturing Overhead Efficiency Variance can be calculated by comparing the standard cost of actual production at the standard number of hours required to produce the actual output, which is multiplied by the standard variable overhead rate per hour, with the actual variable overhead cost incurred in producing the actual output.

A study was carried out to compare the effectiveness of the two vaccines A and B. The study reported that of the 900 adults who were randomly assigned vaccine A, 18 got the virus. Of the 600 adults who were randomly assigned vaccine B, 30 got the virus (round to two decimal places as needed).

Construct a 95% confidence interval for comparing the two vaccines (define vaccine A as population 1 and vaccine B as population 2

Suppose the two vaccines A and B were claimed to have the same effectiveness in preventing infection from the virus. A researcher wants to find out if there is a significant difference in the proportions of adults who got the virus after vaccinated using a significance level of 0.05.

What is the test statistic?

Answers

The test statistic is approximately -2.99 using the significance level of 0.05.

To compare the effectiveness of vaccines A and B, we can use a hypothesis test for the difference in proportions. First, we calculate the sample proportions:

p1 = x1 / n1 = 18 / 900 ≈ 0.02

p2 = x2 / n2 = 30 / 600 ≈ 0.05

Where x1 and x2 represent the number of adults who got the virus in each group.

To construct a 95% confidence interval for comparing the two vaccines, we can use the following formula:

CI = (p1 - p2) ± Z * √[(p1 * (1 - p1) / n1) + (p2 * (1 - p2) / n2)]

Where Z is the critical value corresponding to a 95% confidence level. For a two-tailed test at a significance level of 0.05, Z is approximately 1.96.

Plugging in the values:

CI = (0.02 - 0.05) ± 1.96 * √[(0.02 * (1 - 0.02) / 900) + (0.05 * (1 - 0.05) / 600)]

Simplifying the equation:

CI = -0.03 ± 1.96 * √[(0.02 * 0.98 / 900) + (0.05 * 0.95 / 600)]

Calculating the values inside the square root:

√[(0.02 * 0.98 / 900) + (0.05 * 0.95 / 600)] ≈ √[0.0000218 + 0.0000792] ≈ √0.000101 ≈ 0.01005

Finally, plugging this value back into the confidence interval equation:

CI = -0.03 ± 1.96 * 0.01005

Calculating the confidence interval:

CI = (-0.0508, -0.0092)

Therefore, the 95% confidence interval for the difference in proportions (p1 - p2) is (-0.0508, -0.0092).

Now, to find the test statistic, we can use the following formula:

Test Statistic = (p1 - p2) / √[(p1 * (1 - p1) / n1) + (p2 * (1 - p2) / n2)]

Plugging in the values:

Test Statistic = (0.02 - 0.05) / √[(0.02 * (1 - 0.02) / 900) + (0.05 * (1 - 0.05) / 600)]

Simplifying the equation:

Test Statistic = -0.03 / √[(0.02 * 0.98 / 900) + (0.05 * 0.95 / 600)]

Calculating the values inside the square root:

√[(0.02 * 0.98 / 900) + (0.05 * 0.95 / 600)] ≈ √[0.0000218 + 0.0000792] ≈ √0.000101 ≈ 0.01005

Finally, plugging this value back into the test statistic equation:

Find z that such 8.6% of the standard normal curve lies to the right of z.

Answers

Therefore, we have to take the absolute value of the z-score obtained. Thus, the z-score is z = |1.44| = 1.44.

To determine z such that 8.6% of the standard normal curve lies to the right of z, we can follow the steps below:

Step 1: Draw the standard normal curve and shade the area to the right of z.

Step 2: Look up the area 8.6% in the standard normal table.Step 3: Find the corresponding z-score for the area using the table.

Step 4: Take the absolute value of the z-score obtained since we want the area to the right of z.

Step 1: Draw the standard normal curve and shade the area to the right of z

The standard normal curve is a bell-shaped curve with mean 0 and standard deviation 1. Since we want to find z such that 8.6% of the standard normal curve lies to the right of z, we need to shade the area to the right of z as shown below:

Step 2: Look up the area 8.6% in the standard normal table

The standard normal table gives the area to the left of z.

To find the area to the right of z, we need to subtract the area from 1.

Therefore, we look up the area 1 – 0.086 = 0.914 in the standard normal table.

Step 3: Find the corresponding z-score for the area using the table

The standard normal table gives the z-score corresponding to the area 0.914 as 1.44.

Step 4: Take the absolute value of the z-score obtained since we want the area to the right of z

The area to the right of z is 0.086, which is less than 0.5.

Therefore, we have to take the absolute value of the z-score obtained.

Thus, the z-score is z = |1.44| = 1.44.

Z-score is also known as standard score, it is the number of standard deviations by which an observation or data point is above the mean of the data set. A standard normal distribution is a normal distribution with mean 0 and standard deviation 1.

The area under the curve of a standard normal distribution is equal to 1. The area under the curve of a standard normal distribution to the left of z can be found using the standard normal table.

Similarly, the area under the curve of a standard normal distribution to the right of z can be found by subtracting the area to the left of z from 1.

In this problem, we need to find z such that 8.6% of the standard normal curve lies to the right of z. To find z, we need to perform the following steps.

Answers

The work done in stretching the spring from 16 cm to 18 cm is 0.10 J.

Calculation of spring constant The given spring has a natural length of 16 cm. When it is stretched to 20 cm, a force of 21 N is required. We know that the spring constant is given by the force required to stretch a spring per unit of extension. It can be calculated as follows; k = F / x where k is the spring constant F is the force required to stretch the spring x is the extension produced by the force Substituting the given values in the above formula, we get; k = 21 N / (20 cm - 16 cm) = 5 N/cm = 500 N/m Therefore, the exact value of the spring constant is 500 N/m.(b) Calculation of work done in stretching the spring from 16 cm to 18 cm The work done in stretching a spring from x1 to x2 is given by the area under the force-extension graph from x1 to x2.

The force-extension graph for a spring is a straight line passing through the origin with a slope equal to the spring constant. As we know that W = 1/2kx²The extension produced in stretching the spring from 16 cm to 18 cm is:x2 - x1 = 18 cm - 16 cm = 2 cm The work done in stretching the spring from 16 cm to 18 cm is given by:W = (1/2)k(x2² - x1²) = (1/2)(500 N/m)(0.02 m)² = 0.10 J.

Question 6 of 12 View Policies Current Attempt in Progress Solve the given triangle. Round your answers to the nearest integer. Ax Y≈ b= eTextbook and Media Sve for Later 72 a = 3, c = 5, B = 56°

Answers

The angles A, B, and C are approximately 65°, 56° and 59°, respectively.

Given data:

a = 3, c = 5, B = 56°

In a triangle ABC, we have the relation:

a/sin(A) = b/sin(B) = c/sin(C)

The given angle B = 56°

Thus, sin B = sin 56° = b/sin(B)

On solving, we get b = c sin B/ sin C= 5 sin 56°/ sin C

Now, we need to find the value of angle A using the law of cosines:

cos A = (b² + c² - a²)/2bc

Putting the values of a, b and c in the above formula, we get:

cos A = (25 sin² 56° + 9 - 25)/(2 × 3 × 5)

cos A = (25 × 0.5543² - 16)/(30)

cos A = 0.4185

cos⁻¹ 0.4185 = 65.47°

We can find angle C by subtracting the sum of angles A and B from 180°.

C = 180° - (A + B)C = 180° - (65.47° + 56°)C = 58.53°

Thus, the angles A, B, and C are approximately 65°, 56° and 59°, respectively.

Measures of angles ACB and AC are is m(ACB) = 64°, m(AC) = 146°

What is the measure of angle ACB?

Given that m(AB) = 64° and m(ABC) = 73°, we can find the measures of m(ACB) and m(AC) using the properties of angles in a circle.

First, we know that the measure of a central angle is equal to the measure of the intercepted arc. In this case, m(ACB) is the central angle, and the intercepted arc is AB. Therefore, m(ACB) = m(AB) = 64°.

Next, we can use the property that an inscribed angle is half the measure of its intercepted arc. The angle ABC is an inscribed angle, and it intercepts the arc AC. Therefore, m(AC) = 2 * m(ABC) = 2 * 73° = 146°.

To summarize:

m(ACB) = 64°

m(AC) = 146°

These are the measures of angles ACB and AC, respectively, based on the given information.

Sample standard deviation, s = 2

Sample size, n = 11

Significance level = 0.10

We can find the standard error of the mean, SE using the below formula:

SE = s/√n where, s is the sample standard deviation, and n is the sample size.

Substituting the values,SE = 2/√11 SE ≈ 0.6

Using the t-distribution table, with 10 degrees of freedom at a 0.10 significance level, we can find the t-value.

Suppose a, b, c, n are positive integers such that a+b+c=n. Show that n-1 (a,b,c) = (a-1.b,c) + (a,b=1,c) + (a,b,c - 1) (a) (3 points) by an algebraic proof; (b) (3 points) by a combinatorial proof.

Answers

a) We have shown that n-1 (a, b, c) = (a-1, b, c) + (a, b-1, c) + (a, b, c-1) algebraically. b) Both sides of the equation represent the same combinatorial counting, which proves the equation.

(a) Algebraic Proof:

Starting with the left-hand side, n-1 (a, b, c):

Expanding it, we have n-1 (a, b, c) = (n-1)a + (n-1)b + (n-1)c.

Now, let's look at the right-hand side:

(a-1, b, c) + (a, b-1, c) + (a, b, c-1)

Expanding each term, we have:

(a-1)a + (a-1)b + (a-1)c + a(b-1) + b(b-1) + (b-1)c + ac + bc + (c-1)c

Combining like terms, we get:

a² - a + ab - b + ac - c + ab - b² + bc - b + ac + bc - c² + c

Simplifying further:

a² + ab + ac - a - b - c - b² - c² + 2ab + 2ac - 2b - 2c

Rearranging the terms:

a² + 2ab + ac - a - b - c - b² + 2ac - 2b - c² - 2c

Combining like terms again:

(a² + 2ab + ac - a - b - c) + (-b² + 2ac - 2b) + (-c² - 2c)

Notice that the first term is equal to (a, b, c) since it represents the sum of the original numbers a, b, c.

The second term is equal to (a-1, b, c) since we have subtracted 1 from b.

The third term is equal to (a, b, c-1) since we have subtracted 1 from c.

Therefore, the right-hand side simplifies to:

(a, b, c) + (a-1, b, c) + (a, b, c-1)

(b) Combinatorial Proof:

Let's consider a combinatorial interpretation of the equation a+b+c=n. Suppose we have n distinct objects and we want to partition them into three groups: Group A with a objects, Group B with b objects, and Group C with c objects.

On the left-hand side, n-1 (a, b, c), we are selecting n-1 objects to distribute among the groups. This means we have n-1 objects to distribute among a+b+c-1 spots (since we have a+b+c total objects and we are leaving one spot empty).

Now, let's look at the right-hand side:

(a-1, b, c) + (a, b-1, c) + (a, b, c-1)

For (a-1, b, c), we are selecting a-1 objects to distribute among a+b+c-1 spots, leaving one spot empty in Group A.

For (a, b-1, c), we are selecting b-1 objects to distribute among a+b+c-1 spots, leaving one spot empty in Group B.

For (a, b, c-1), we are selecting c-1 objects to distribute among a+b+c-1 spots, leaving one spot empty in Group C.

The sum of these three expressions represents selecting n-1 objects to distribute among a+b+c-1 spots, leaving one spot empty.

Hence, we have shown that n-1 (a, b, c) = (a-1, b, c) + (a, b-1, c) + (a, b, c-1) by a combinatorial proof.

Let's solve for x.2x - 2 = 0⇒ 2x = 2⇒ x = 1Therefore, f '(1) = 2(1) - 2 = 0The critical point is x = 1.Now, we need to test if this critical point gives an absolute maximum or minimum.To do this, we can check the value of f(x) at this point as well as the values of f(x) at the endpoints of the domain of x. Here, the domain is -∞ < x < ∞.Let's begin by calculating f(x) at the critical point.x = 1⇒ f(1) = (1)² - 2(1) + 5= 4Therefore, the function has a maximum at x = 1.

Now, let's check the values of f(x) at the endpoints of the domain.x → -∞⇒ f(x) → ∞x → ∞⇒ f(x) → ∞Therefore, there are no minimum values of the function.To summarize, the absolute maximum of the function f(x) = x² - 2x + 5 is 4 and there is no absolute minimum value of the function as f(x) approaches infinity for both positive and negative values of x.

What does a linear model look like? Explain what all of the pieces are? 2) What does an exponential model look like? Explain what all of the pieces are? 3) What is the defining characteristic of a linear model? 4) What is the defining characteristic of an exponential model?

Answers

A linear model is that it represents a constant Rate of change between the two variables.

1) A linear model is a mathematical representation of a relationship between two variables that forms a straight line when graphed. The equation of a linear model is typically of the form y = mx + b, where y represents the dependent variable, x represents the independent variable, m represents the slope of the line, and b represents the y-intercept. The slope (m) determines the steepness of the line, and the y-intercept (b) represents the point where the line intersects the y-axis.

2) An exponential model is a mathematical representation of a relationship between two variables where one variable grows or decays exponentially with respect to the other. The equation of an exponential model is typically of the form y = a * b^x, where y represents the dependent variable, x represents the independent variable, a represents the initial value or starting point, and b represents the growth or decay factor. The growth or decay factor (b) determines the rate at which the variable changes, and the initial value (a) represents the value of the dependent variable when the independent variable is zero.

3) The defining characteristic of a linear model is that it represents a constant rate of change between the two variables. In other words, as the independent variable increases or decreases by a certain amount, the dependent variable changes by a consistent amount determined by the slope. This results in a straight line when the data points are plotted on a graph.

4) The defining characteristic of an exponential model is that it represents a constant multiplicative rate of change between the two variables. As the independent variable increases or decreases by a certain amount, the dependent variable changes by a consistent multiple determined by the growth or decay factor. This leads to a curve that either grows exponentially or decays exponentially, depending on the value of the growth or decay factor.

A swim team has 75 members and there is a 12% absentee rate per
team meeting.
Find the probability that at a given meeting, exactly 10 members
are absent.

Answers

To find the probability that exactly 10 members are absent at a given meeting, we can use the binomial probability formula. In this case, we have a fixed number of trials (the number of team members, which is 75) and a fixed probability of success (the absentee rate, which is 12%).

The binomial probability formula is given by:

[tex]\[ P(X = k) = \binom{n}{k} \cdot p^k \cdot (1-p)^{n-k} \][/tex]

where:

- [tex]\( P(X = k) \)[/tex] is the probability of exactly k successes

- [tex]\( n \)[/tex] is the number of trials

- [tex]\( k \)[/tex] is the number of successes

- [tex]\( p \)[/tex] is the probability of success

In this case, [tex]\( n = 75 \), \( k = 10 \), and \( p = 0.12 \).[/tex]

Using the formula, we can calculate the probability:

[tex]\[ P(X = 10) = \binom{75}{10} \cdot 0.12^{10} \cdot (1-0.12)^{75-10} \][/tex]

The binomial coefficient [tex]\( \binom{75}{10} \)[/tex] can be calculated as:

[tex]\[ \binom{75}{10} = \frac{75!}{10! \cdot (75-10)!} \][/tex]

Calculating these values may require a calculator or software with factorial and combination functions.

After substituting the values and evaluating the expression, you will find the probability that exactly 10 members are absent at a given meeting.

e 6xy dv, where e lies under the plane z = 1 x y and above the region in the xy-plane bounded by the curves y = x , y = 0, and x = 1

Answers

The problem involves evaluating the integral of 6xy over a specific region in three-dimensional space. The region lies beneath the plane z = 1 and is bounded by the curves y = x, y = 0, and x = 1 in the xy-plane.

To solve this problem, we need to integrate the function 6xy over the given region. The region is defined by the plane z = 1 above it and the boundaries in the xy-plane: y = x, y = 0, and x = 1.

First, let's determine the limits of integration. Since y = x and y = 0 are two of the boundaries, the limits of y will be from 0 to x. The limit of x will be from 0 to 1.

Now, we can set up the integral:

∫∫∫_R 6xy dv,

where R represents the region in three-dimensional space.

To evaluate the integral, we integrate with respect to z first since the region is bounded by the plane z = 1. The limits of z will be from 0 to 1.

Next, we integrate with respect to y, with limits from 0 to x.

Finally, we integrate with respect to x, with limits from 0 to 1.

By evaluating the integral, we can find the numerical value of the expression 6xy over the given region.

what is the probability that the length of stay in the icu is one day or less (to 4 decimals)?

Answers

The probability that the length of stay in the ICU is one day or less is approximately 0.0630 to 4 decimal places.

To calculate the probability that the length of stay in the ICU is one day or less, you need to find the cumulative probability up to one day.

Let's assume that the length of stay in the ICU follows a normal distribution with a mean of 4.5 days and a standard deviation of 2.3 days.

Using the formula for standardizing a normal distribution, we get:z = (x - μ) / σwhere x is the length of stay, μ is the mean (4.5), and σ is the standard deviation (2.3).

To find the cumulative probability up to one day, we need to standardize one day as follows:

z = (1 - 4.5) / 2.3 = -1.52

Using a standard normal distribution table or a calculator, we find that the cumulative probability up to z = -1.52 is 0.0630.

Therefore, the probability that the length of stay in the ICU is one day or less is approximately 0.0630 to 4 decimal places.

Answers

The value of the residual at that point is 0.9.

The regression model is yhat = 11.5+0.9x. Given that the actual value of y when x = 14 is 25. We want to find the residual at that point. Residuals represent the difference between the actual value of y and the predicted value of y. To find the residual, we first need to find the predicted value of y (yhat) when x = 14. Substitute x = 14 into the regression model: yhat = 11.5 + 0.9x= 11.5 + 0.9(14)= 11.5 + 12.6= 24.1.

Therefore, the predicted value of y (yhat) when x = 14 is 24.1.The residual at that point is the difference between the actual value of y and the predicted value of y: Residual = Actual value of y - Predicted value of y= 25 - 24.1= 0.9.

The known solutions to f(x) = g(x) can be determined by finding the values of x for which f(x) and g(x) are equal. In this case, analyzing the given table, we find that the only known solution to f(x) = g(x) is x = 3.

By examining the values of f(x) and g(x) from the given table, we can observe that they intersect at x = 3. For x = 1, f(1) = 3 and g(1) = 3, which means they are equal. However, this is not considered a solution to f(x) = g(x) since it is not an intersection point. Moving forward, at x = 3, we have f(3) = 9 and g(3) = 9, showing that f(x) and g(x) are equal at this point. Similarly, at x = 5, f(5) = 3 and g(5) = 3, but again, this is not considered an intersection point. At x = 7, f(7) = 4 and g(7) = 4, and at x = 9, f(9) = 12 and g(9) = 12. None of these points provide solutions to f(x) = g(x) as they do not intersect. Finally, at x = 11, f(11) = 6 and g(11) = 6, but this point also does not satisfy the condition.

Answers

Thus, if we choose z to be a negative value instead of a positive value, then we would get the opposite inequality.

The statement "For any positive value z, it is always true that P(Z > z) > P(T > z), where Z~ N(0,1), and T ~ Taf, for some finite df value" is false. This is because both normal and t distributions have a symmetric distribution.

Explanation: Let Z be a random variable that has a standard normal distribution, i.e. Z ~ N(0, 1). Then we have, P(Z > z) = 1 - P(Z < z) = 1 - Φ(z), where Φ is the cumulative distribution function (cdf) of the standard normal distribution. Similarly, let T be a random variable that has a t distribution with n degrees of freedom, i.e. T ~ T(n).Then we have, P(T > z) = 1 - P(T ≤ z) = 1 - F(z), where F is the cdf of the t distribution with n degrees of freedom. The statement "P(Z > z) > P(T > z)" is equivalent to Φ(z) < F(z), for any positive value of z. However, this is not always true. Therefore, the statement is false. The reason for this is that both normal and t distributions have a symmetric distribution. The standard normal distribution is symmetric about the mean of 0, and the t distribution with n degrees of freedom is symmetric about its mean of 0 when n > 1.

Answers

The probability of X = 0 for a binomial random variable with n = 4 and p = 0.45 is approximately 0.0897.

To compute the probability of X = 0 for a binomial random variable, we can use the probability mass function (PMF) formula:

[tex]P(X = k) = C(n, k) * p^k * (1 - p)^(n - k)[/tex]

Where:

- P(X = k) is the probability of X taking the value k.

- C(n, k) is the binomial coefficient, given by C(n, k) = n! / (k! * (n - k)!).

- n is the number of trials.

- p is the probability of success on each trial.

- k is the desired number of successes.

In this case, we have n = 4 and p = 0.45. We want to find P(X = 0), so k = 0. Plugging in these values, we get:

[tex]P(X = 0) = C(4, 0) * 0.45^0 * (1 - 0.45)^(4 - 0)[/tex]

The binomial coefficient C(4, 0) is equal to 1, and any number raised to the power of 0 is 1. Thus, the calculation simplifies to:

[tex]P(X = 0) = 1 * 1 * (1 - 0.45)^4P(X = 0) = 1 * 1 * 0.55^4P(X = 0) = 0.55^4[/tex]

Calculating this expression, we find:

P(X = 0) ≈ 0.0897

Therefore, the probability of X = 0 for the binomial random variable is approximately 0.0897.

the reaction r to an injection of a drug is related to the dose x (in milligrams) according to the following. r(x) = x2 700 − x 3 find the dose (in mg) that yields the maximum reaction.

Answers

the dose (in mg) that yields the maximum reaction is 1800 mg (rounded off to the nearest integer).

The given equation for the reaction r(x) to an injection of a drug related to the dose x (in milligrams) is:

r(x) = x²⁷⁰⁰ − x³

The dose (in mg) that yields the maximum reaction is to be determined from the given equation.

To find the dose (in mg) that yields the maximum reaction, we need to differentiate the given equation w.r.t x as follows:

r'(x) = 2x(2700) - 3x² = 5400x - 3x²

Now, we need to equate the first derivative to 0 in order to find the maximum value of the function as follows:

r'(x) = 0

⇒ 5400x - 3x² = 0

⇒ 3x(1800 - x) = 0

⇒ 3x = 0 or 1800 - x = 0

⇒ x = 0

or x = 1800

The above two values of x represent the critical points of the function.

Since x can not be 0 (as it is a dosage), the only critical point is:

x = 1800

Now, we need to find out whether this critical point x = 1800 is a maximum point or not.

For this, we need to find the second derivative of the given function as follows:

r''(x) = d(r'(x))/dx= d/dx(5400x - 3x²) = 5400 - 6x

Now, we need to check the value of r''(1800).r''(1800) = 5400 - 6(1800) = -7200

Since the second derivative r''(1800) is less than 0, the critical point x = 1800 is a maximum point of the given function. Therefore, the dose (in mg) that yields the maximum reaction is 1800 mg (rounded off to the nearest integer).

Therefore, we calculate the expected frequencies under the null hypothesis that the clothing type (superhero or street clothes) has no effect on how hard the boys work, using the formula

E = (Row total × Column total)/n, where n is the total count.

The expected values are as follows:

Superhero Street Clothes TotalHard Work

25                  25                          50

Less Hard Work 25 25 50

Total 50 50 100

The chi-squared statistic is given by the formula χ² = ∑(O - E)² / E

where O is the observed frequency and E is the expected frequency.

The calculated value of chi-squared is as follows:

χ² = [(30 - 25)²/25 + (20 - 25)²/25 + (20 - 25)²/25 + (30 - 25)²/25]χ²

= 2.0

The degrees of freedom for the test is df = (r - 1)(c - 1) where r is the number of rows and c is the number of columns in the contingency table.

Here, we have df = (2 - 1)(2 - 1) = 1.

At a 0.05 level of significance, the critical value of chi-squared with 1 degree of freedom is 3.84. Since our calculated value of chi-squared (2.0) is less than the critical value of chi-squared (3.84), we fail to reject the null hypothesis.

Therefore, we can conclude that there is not enough evidence to suggest that the clothing type has an effect on how hard the boys work.
