Question

A researcher wants to examine whether there are sex differences in physical activity in chronic alcoholics. They conduct a study in which they recruit 31 male and 31 female chronic alcoholics and administer a questionnaire designed to collect information about an individual’s self-report of type and amount of physical activity. They find that male chronic alcoholics, on average, exercise for 210 minutes/week (SS1 = 4,200) whereas female chronic alcoholics exercise for 200 minutes/week (SS2 = 4,115). What conclusion would the researcher draw if α = 0.01?
