Step-by-step explanation:
6n-3
n = 1: 6(1) - 3 = 3
n = 2: 6(2) - 3 = 9

Six Hundred Thousand One Hundred and Eight
The Center for the Study of Violence wants to determine whether a conflict-resolution program in a particular high school alters aggressive behavior among its students. For 5 students, aggression was measured both before and after they participated in the conflict-resolution course. Their scores were the following (higher scores indicate greater aggressiveness).
Before Participating After Participating
10 8
3 3
4 1
8 5
8 7
Required:
a. What is the test statistic
b. What are the degrees of freedom
c. Do you reject the null (at alpha = 0.05)
d. What do your results indicate
Answer:
A.) 3.096 ; b.) 4 ; C). We reject the Null
D.) There is significant evidence to support the claim that conflict resolution program reduces level of aggression in STUDENTS.
Step-by-step explanation:
This is a paired test:
Given the data:
Before (x) __ After (y) __ difference (x - y)
10 ______ 8 ______ 2
3 _______ 3 ______ 0
4 _______ 1 _______3

H0 : μx = μy
H1: μx > μy
dbar = Σd / n ; n = sample size
dbar = 9 / 5 = 1.8
From calculator :
Standard deviation of d, Sd = 1.30
Test statistic = dbar ÷ (Sd / √n)
Test statistic = 1.8 ÷0.5813776
Test statistic = 3.096
Pvalue from test statistic :
df = n - 1 = 5 - 1 = 4
Pvalue, 0.05, 4 = 0.018
Since Pvalue < α ; We reject the Null
We conclude that, there is significant evidence to support the claim that conflict resolution program reduces level of aggression in students.

On a standardized exam, the scores are normally distributed with a mean of 200 and
a standard deviation of 50. Find the Z-score of a person who scored 140 on the exam.
Answer:
First, compute the z-score:
z = (x-μ)/σ = (650-500)/100 = 150/100 = 1.5
Now look up the percentile for z = 1.5 on a z-score table (http://www.z-table.com/). The percentile, p(z=1.5), is the percent of people who scored 650 or less. The percent who scored more than 650 is 1-p(z=1.5). Multiply that by the 1200 students to get the number who scored more than 650. Round to the nearest whole number (because you can't have a fraction of a person).
For the given data the value of the z score will be 1.5
What is the standard deviation?It is referred to as a measure of data dispersal since it provides information on how widely the data is dispersed.
[tex]\rm \sigma = \sqrt{\dfrac{ \sum (x_i-X)}{n}[/tex]
σ stands for the standard deviation
x is the value from the data set
X is the data set mean
n is the number of observations
It is given that, On a standardized exam, the scores are normally distributed with a mean of 200 and a standard deviation of 50.
The Z-score of a person who scored 140 on the exam is as,
z = (x-μ)/σ
z = (650-500)/100
z = 150/100
z = 1.5
Thus, the value of the z score will be 1.5

Brandon's car used 3/4 of a gallon to travel 13 1/2 miles. How many miles can the car go
on one gallon of gas?
Answer:
12
Step-by-step explanation:
Brandon's car can go in one gallon gas= 18 miles
Step-by-step explanation:Definition of gallonIn the United States, the gallon is a unit of measurement for liquids such as gasoline, water, and milk. If your car's tank is nearly empty, you should stop and purchase at least a few additional gallons of gas. A gallon of liquid is equal to 4 quarts or 3.785 liters.
Brandon's car used 3/4 of a gallon to travel 13 1/2 miles.
3/4 of a gallon(G)= 13 1/2 miles
3/4*G=27/2
G=18 miles
Hence, Brandon's car can go in one gallon gas= 18 miles.

Graph the equation. y=4(x +6)(x +4) This is a khan academy question and just write the points please
Answer:
Please see the image below.
Step-by-step explanation:
A farmer wants to know the effect of using various amounts of fertilizer in relation to the yield of his crops. Be subdivided a portion of his land into 10 separate but essentially equal plots. He divided the land so that all of the plots had equal exposure to sun, rain, and other environmental conditions. He randomly selected 2 of the 10 plots and spread 2 pounds of fertilizer over each of them. Then he randomly selected 2 of the remaining plots and spread 3 pounds of fertilizer over each of them. He continued with the last sets of plots in the same manner, spreading 4, then 5, then 6 pounds of fertilizer over each of them. Below is a computer output for linear regression of amount of fertilizer versus yield for the 10 plots of land.

What is the equation of the least squares regression line from this sample?
Answer:
The equation of line is
[tex]\text{yield}=1.15\times \text{fertilizer}+10.1[/tex]
Step-by-step explanation:
The general equation of line is given as
[tex]y=mx+b[/tex]
where
y is the dependent variable which is yield in this case.
x is the independent variable which is fertilizer in this case
m is the coefficient of the fertilizer whose value is 1.150 from the given values.
b is the constant whole value is 10.100 from the given values.
Thus the equation becomes.
[tex]\text{yield}=1.15\times \text{fertilizer}+10.1[/tex]

$1000 is invested at 2.9% annual interest for 6 months.
a. Simple Interest b. Compound Interest
Answer:
a. Simple interest = $174
b. Compund interest = $1187.1
Step-by-step explanation:
Given the following data;
Principal, P = $1000
Interest, R = 2.9%
Time, T = 6 months
a. To find the simple interest;
S.I = (PRT)/100
S.I = (1000*2.9*6)/100
S.I = 17400/100
S.I = $174
b. To find the compound interest;
[tex] A = P(1 + \frac{r}{100})^{t}[/tex]
Substituting into the formula, we have;
[tex] A = 1000(1 + \frac{2.9}{100})^{6}[/tex]
[tex] A = 1000(1 + 0.029)^{6} [/tex]
[tex] A = 1000(1.029)^{6} [/tex]
[tex] A = 1000(1.1871)[/tex]
A = $1187.1

Sally's bank account had a balance of 230 at the beginning of the month. She had two deposits of 50 and 420 and just one withdrawal of 190. Her balance at the end of the month was $______ ?
Answer:
510
Step-by-step explanation:
Sally bank account had a beginning balance of 230
She made two deposits of 50 and 420
50+420
= 470
She made a withdrawal of 190
Therefore her balance at the end of the month can be calculated as follows
470+230
= 700
= 700-190
= 510
Hence the balance at the end of the month is 510

What is the theoretical probability that the spinner below will land on 6 if someone spins it 48 times?
Answer:
1/4 or 12*
Step-by-step explanation:
There are 8 possibilities. 2 of them are 6.
2/8=1/4
1/4 of 48 is 12
*The theoretical probability doesn’t change no matter how many times you spin the spinner. It will always be 1/4. (Or 0.25, or 25%). That could be what they’re asking. If you spun it 48 times, it would probably land on a six 12 times. That could also be what they’re asking for. 12:48 = 1:4.
