This question has 6 parts. Each of the 6 parts (Part A - Part F)
has a dropdown list of possible answers. Choose the best answer
from the dropdown list for EACH part of the question below. The
same psychologists are now interested in determining if there is
any difference in anxiety levels of participants before and after a
group therapy program. Anxiety levels of a sample of participants
both before and after the program are listed below: Patient #
Anxiety level before the group therapy program Anxiety level after
the group therapy program 1 68 64 2 75 73 3 54 55 4 89 83 5 66 65
You are informed the estimated standard error of the mean
differences (s \overline{D} ) is 1.21. Using the appropriate
two-tailed hypothesis test (a two related samples t-test) with the
H0: µD = 0 and H1: µD ≠ 0, calculate the test statistic and make a
decision about the null hypothesis using an alpha (α) level of
0.01. You will use the information above to complete the question
parts below for a two related samples t-test. Part A: What is the
degrees of freedom (df) associated with your test? PART A ANSWER: [
Select ] Part B:. Which of the following represents the appropriate
critical value(s), testing at an alpha level (α) of 0.01? PART B
ANSWER: [ Select ] Part C: Calculate the sample mean of difference
scores ( \overline{D} ) (which you will use in the calculation of
your test statistic):? PART C ANSWER: [ Select ] Part D:What is the
t-statistic associated with your test? (rounded to the nearest
hundredth) - see note above for the value of the standard error of
the mean differences. PART D ANSWER: [ Select ] Part E: Given your
test results, what is your decision about the null hypothesis? PART
E ANSWER: [ Select ] Part F: The best interpretation of the
appropriate decision regarding the null hypothesis would be: "Based
on our study, we [ Select ] enough evidence to conclude that there
appears to be a difference in the mean anxiety levels of the
population of people before and after the group therapy
program."
