Question

A social psychologist predicts that college students will benefit from a self-efficacy program for professional athletes. A sample of students is drawn from a university whose students have an average of 54 for self-efficacy. The sample of students goes through the program for six weeks and afterwards are given a self-efficacy questionnaire. What can the psychologist conclude with an α of 0.01? The self-efficacy scores for the sample after six weeks are:
50, 61, 80, 46, 94, 51, 37, 85, 77, 70, 77.(this is the data for the sample)

a) What is the appropriate test statistic?
---Select--- na z-test One-Sample t-test Independent-Samples t-test Related-Samples t-test
Population:
---Select--- students at the university self-efficacy program sample of students from the university college students six weeks
Sample:
---Select--- students at the university self-efficacy program sample of students from the university college students six weeks

b) Compute the appropriate test statistic(s) to make a decision about H₀.
(Hint: Make sure to write down the null and alternative hypotheses to help solve the problem.)
critical value =  ; test statistic =  
Decision:  ---Select--- Reject H0 Fail to reject H0

c) If appropriate, compute the CI. If not appropriate, input "na" for both spaces below.
[  ,  ]
Compute the corresponding effect size(s) and indicate magnitude(s).
If not appropriate, input and/or select "na" below.
d =  ;   ---Select--- na trivial effect small effect medium effect large effect
r² =  ;   ---Select--- na trivial effect small effect medium effect large effect

d) Make an interpretation based on the results.

The self-efficacy of students that undergo the self-efficacy program is higher than those at the university.The self-efficacy of students that undergo the self-efficacy program is less than those at the university.    The self-efficacy of students that undergo the self-efficacy program is not significantly different than those at the university.
