Use the following information to answer questions 1-2. Sasha wants to know if there are sex differences in the effect of exercise on executive function for older adults. She recruits 20 65+ subjects, 10 male and 10 female, and splits her sample into two groups. One group served as a wait-list* control, while the other group participated in a mild exercise program over the course of 8 weeks. At the end of the 8 weeks, she tests executive functioning using a test of reaction time in an executive functioning task (the lower a participant's score, the better). The scores are listed on the following table. *wait-list control means that the control group will also receive the intervention later, but for now they serve as the control. 1| Factor B: Sex Female Male Factor A: Exercise Use the following information to answer questions 3-4.
