2. The number of violent crimes committed in a day possesses a distribution with a mean of 2.8 crimes per day and a standard deviation of 4 crimes per day. A random sample of 100 days was observed, and the sample mean number of crimes for the sample was calculated. Describe the sampling distribution of the sample means. (5 points) a.) shape unknown with mean of 2.8 and a standard deviation of 0.4
Options :
a.) shape unknown with mean of 2.8 and a standard deviation of 0.4 b.) approximately normal with mean of 2.8 and standard deviation of 4 C.) shape unknown with mean of 2.8 and standard deviation of 4 d.) approximately normal with mean of 2.8 and standard deviation of 0.4
Answer: d.) approximately normal with mean of 2.8 and standard deviation of 0.4.
Step-by-step explanation:
Given that :
Population Mean (m) = 2.8
Population Standard deviation (s) = 4
Sample size = 100
The mean of the sampling distribution is equal to the population mean, according to the central limit theorem. As the size of the sample increases, the mean if the sample distribution converges to that if the population mean.
Hence, sample mean = 2.8
The sample standard deviation (standard error) :
Standard Error = population standard deviation / √sample size
= s/√n
= 4 / √100
= 4/10
= 0.4
Using the Central Limit Theorem, it is found that the correct description of the sampling distribution of the sample means is:
Approximately normal, with mean of 2.8 and standard deviation of 0.4.
The Central Limit Theorem establishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].
For a variable of unknown distribution, the Central Limit Theorem can be applied if the sample size is larger than 30.In this problem, the population has an unknown distribution, with mean [tex]\mu = 2.8[/tex] and standard deviation [tex]\sigma = 4[/tex]
The sampling distribution of the sample means of size 100 has:
Approximately normal shape, as the sample size is [tex]n = 100 > 30[/tex].Mean [tex]\mu = 2.8[/tex]Standard deviation [tex]s = \frac{4}{\sqrt{100}} = 0.4[/tex].A similar problem is given at https://brainly.com/question/14099217

Step-by-step explanation:
You measure 22 watermelons' weights, and find they have a mean weight of 36 ounces. Assume the population standard deviation is 6.9 ounces. Based on this, construct a 95% confidence interval for the true population mean watermelon weight. Give your answers as decimals, to two places
Answer:
Step-by-step explanation:
Confidence interval formula is expressed as;
CI = xbar ±(z*s/√n)
xbar is the mean = 36
z is the z score at 95% CI = 1.96
s is the standard deviation = 6.9
n is the sample size = 22
Substitute
CI = 36 ±(1.96*6.9/√22)
CI = 36 ±(1.96*6.9/4.6904)
CI = 36 ±(1.96*1.4711)
CI = 36 ± 2.8833
CI = (36 - 2.8833, 36 + 2.8833)
CI = (33.1167, 38.8833)
Hence the 95% CI for the true population mean is 33.12<x<38.88

2. The Martian Zoological Society has a unique display of the native monocephalous fauna:
Tripods (three feet each) and Pentapods (five feet each). When I was there, I counted 20 heads
and 84 feet.
a.) Draw a picture to find the solution.
b.) Set up a system of equations to make sure your "picture" answer is correct. Show your
work.
Answer:
There are 12 pentapods and 8 Tripods, which in total add up to 84 feet.
Step-by-step explanation:
Given that both the Tripods and the Pentapods have, at least, 3 feet (the Pentapods have 5), and that in total between both groups they add 20 heads and 84 feet, the following logical reasoning can be made:
If there are 20 heads, there are 20 Martians in all. Each of them has, at least, 3 feet, with which in principle the 20 Martians would add up to a total of 60 feet (20 x 3). Therefore, there is a surplus of 24 feet (84 - 60).
If the Pentapods have 2 feet more than the Tripods, the number of Pentapods in the total Martians is determined by that difference. Thus, if there are 24 feet left, there are 12 Pentapods (24/2).
Therefore, in the group of Martians there are 12 pentapods (12 x 5 = 60) and 8 Tripods (8 x 3 = 24), which in total add up to 84 feet (60 + 24).

Answer:
30.6
Step-by-step explanation:
The sine rule of trigonometry helps us to equate the side of the triangles to the angles of the triangles. The length of the side j is 30.6 cm.
What is Sine rule?The sine rule of trigonometry helps us to equate the side of the triangles to the angles of the triangles. It is given by the formula,
[tex]\dfrac{Sin\ A}{\alpha} =\dfrac{Sin\ A}{\beta} =\dfrac{Sin\ A}{\gamma}[/tex]
where Sin A is the angle and α is the length of the side of the triangle opposite to angle A,
Sin B is the angle and β is the length of the side of the triangle opposite to angle B,
Sin C is the angle and γ is the length of the side of the triangle opposite to angle C.
Given the length of i is 53 cm, while the measure of the ∠I is 120°. Also, the measure of ∠J is 30°. Therefore, the length of the side j is,
[tex]\dfrac{Sin\ A}{\alpha} =\dfrac{Sin\ A}{\beta} =\dfrac{Sin\ A}{\gamma}\\\\\dfrac{Sin\ I}{i} =\dfrac{Sin\ J}{j} \\\\\dfrac{Sin\ 120^o}{53} =\dfrac{Sin\ 30^o}{j} \\\\j = \dfrac{Sin\ 30^o \times 53}{Sin\ 120^o}\\\\j = 30.5995 \approx 30.6\rm\ cm[/tex]
Hence, the length of the side j is 30.6 cm.

1. Translate the following sentence into an equation. The product of six and
a number n is three less than the sum of four and n.
Answer:
6n + 3 = 4 + n
Step-by-step explanation:
Answer:
6n-3=4+n
Step-by-step explanation:
Ok since it is saying "the product of six and a number" it is a multiplication of the two variables 6 and n, which will give you "6n." The next part is "three less than." This is a subtraction cause you are subtracting 3 from 6n. The last part "the sum of four and n." Is an addition because it has the word sum, which will give you 4+n.
Product=multiplication
Less than=subtraction
Sum of= Addition

[tex]-15x+32=13\\-15x=13-32\\-15x=-45\\x=-45/-15\\x=3[/tex]
Step-by-step explanation:
To Solve This Equation You will need to
follow this;Original Equation;
-15x+32=-13
•(Firstly you will Group Like Terms)
-15x=-13-32
•(After Grouping you will go ahead and simplify)
-15x=-13-32
(You will have to add the two negative numbers and note that negative plus negative is still negative even though there is no addition sign there but you'll add them because when there is two negatives without a multiplication or division or any other sign you have to add)
-15x=-13-32
-15x=-45
(Then you proceed to divide both sides by -15)
x=3
This is because -45 divided by -15 is positive 3
Positive 3 because the negative signs cancel each other out.
-6n + 3= 45
