Students in a statistics class at Penn State were asked, “About how many minutes do you typically exercise in a week?" Responses from the women in the class were as follows: 60, 240, 0, 360, 450, 200, 100, 70, 240, 0, 60, 360, 180, 300, 0, 270 Responses from the men in the class were as follows: 180, 300, 60, 480, 0, 90, 300, 14, 600, 360, 120, 0, 240 1. What assumptions or conditions are required if conclusions are to be made about amount of exercise for the population of all Penn State students on the basis of these sample results? 2. Assume that the conditions are met, and conduct a test to determine whether the mean amoun of exercise differs for men and women. This is an independent samples t-test. Do not assume variances are equal so use the unpooled formula. Specify the value of a that you chose to use. Report your t-test result in APA format: t(df) = ,p< .05 (or p > .05 if appropriate)
