Question

A study was done to assess the effectiveness of Acceptance and Commitment Therapy for people with generalized anxiety disorder. The reserachers wanted to know if the treatment decreased or increased the reported levels of anxiety. Six participants were measured before therapy, and after therapy. The dependent variable was the number of reported symptoms. They collected the following data:

 

Patient                             Pre                      Post                   

1                                        21                        15                         

2                                        24                        15        

3                                        21                        17                       

4                                        26                        20                    

5                                       32                        17  





The reseracher decided to use a one-tailed test. Is this correct? Explain why or why not. 

State the null and alternate hypothesis for this study.

Calculate the degrees of freedom. Find the critical value using the appropriate table.

 

The test statistic was calculated and it was -4.16. Using the information you have estabilished in the previous parts of the question, state if you would reject or retain the null hypothesis. Explain why you made that decision? Then explain the finding

The test statistic was calculated and it was -4.16. Using the information you have estabilished in the previous parts of the question, state if you would reject or retain the null hypothesis. Explain why you made that decision? Then explain the findings.
