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).

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
8 _______ 5 ______ 3
8 _______ 7 ______ 1
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.
Mr. Newcomb brought a coffee for himself for $2.38 and for Ms. Latona for $3.65 at Dunkin Donuts. He paid with a $20 bill. How much change did he get?
Answer:
$13.97
Step-by-step explanation:
First, find how much the cost was for the two coffees:
2.38 + 3.65
= 6.03
Find how much change he got by subtracting this from 20:
20 - 6.03
= 13.97
So, he got $13.97 in change
Answer:
Solution :-At first the total money spent by Mr. Newcomb = $ 2.38 + $3.65
=> 6.03
Now
According to the question
Change she get = 20 - 6.03
= 13.97

And
angle RPQ is 65°
Answer:
Step-by-step explanation:
The drawn triangle is in the answered image.
What is triangle ?Triangle is a two dimensional shape having three side and sum of all angles is equals to .
We have,
PQ [tex]= 4.3[/tex] cm
PR [tex]=2.7[/tex] cm
And Angle RPQ [tex]= \angle 65^0[/tex]
Now,
Steps of construction:
Draw a [tex]4.3[/tex] cm long line segment using a ruler. Locate points A and B on both sides of it. With P as the center and radius [tex]2.7[/tex] cm, draw an arc of [tex]\angle65^0[/tex]. With B as the center draw another arc that cuts the previous arc at R.Now, Join PR and QR.Then, PQR is the required triangle.
