(Clearly list each step). Test the difference at both the .05 level of significance. (Alpha = .05) Clearly list each step of hypothesis testing. As part of Step 5, indicate whether the behavioral scientists should recommend group therapy for all depressed people based on evaluation of the null hypothesis.
