You design a study to test the impact of power study programs statistics exam results. You choose 21 students randomly from a statistics class to participate in the study. You randomly assign each student to one of the power groups. Students are later tested with a statistics exam with the material covered in the power study programs. You plan to use an ANOVA to test the impact of each of the power study programs with exam results. Use an alpha level of .05. Report your computed F-ratio, critical region, and your conclusion to accept or reject the null hypothesis.
