A physical therapist wanted to know whether the mean step pulse of men was less than the mean step pulse of women. She randomly selected 52 men and 72 women to participate in the study. Each subject was required to step up and down a 6-inch platform. The pulse of each subject was then recorded. The following results were obtained. Two sample T for Men vs Women Mean StDev SE Mean 1.6 Men Women 90% Cl for mu Men - mu Women (- 10.11, - 2.29) T-Test mu Men = mu Women (vs <) T= -2.64 P 0.0047 DF = 120 52 72 112.5 118.7 11.7 14.4 1.7 (a) State the null and alternative hypotheses.
