A researcher was interested in the effects of exercise on blood pressure. He also wondered if there were any differences due to gender. He solicited the participation of 40 individuals from a senior center. He randomly assigned 10 males and 10 females to go to the mall 3 days a week for 30 minutes of "mall walking." The other 10 males and 10 females stayed at the senior center playing cards. After 8 weeks, he found that the blood pressure of the "mall walkers" was much lower than the "card players." This was true for both males and females.
