Quizplus · Accepted Answer

In order to determine the effectiveness of the new exercise on reducing the rate of heart attacks, the comparison distribution must be a group of people who did not participate in the exercise program. This allows for a comparison between the incidence of heart attacks in those who did the exercise and those who did not. The distribution of people who participate in the exercise program (A) would be the treatment group and not the comparison group. The distribution of people who have heart attacks (C) or who do not have heart attacks (D) would not provide a comparison for the effectiveness of the exercise program.
