Researchers are studying the effects of exercise on resting pulse rates. They have found 20 men to participate in the study. 10 of the men get at least 150 minutes of moderate exercise each week (Group 2) and the other 10 men do not exercise (Group 1). The resting
pulse rate data for the two groups at the end of the study are shown in the table. The pulse rates are in beats per minute
