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.
