... (1) Suppose that we wished to test the null hypothesis that the mean PULSE2 rate for those who ran in place is equal to the mean PULSE2 rate for those who did not ran in place. Which of the following are true? I) It would be reasonable to use a test based on the t(90 d.f.) distribution. II) High pow ...
