A. A professor in physical education conducts an experiment to compare the effects on
nighttime sleep of different amounts of exercise and the time of day when the exercise is
done. There are three levels of exercise (light, moderate, and heavy) and two times of day
(morning and evening). Thirty-six college students who are in good physical condition are
randomly assigned to the six cells such that there are 6 subjects per cell. The subjects
who do heavy exercise jog 9 miles, the subjects who do moderate exercise jog 6 miles,
and the subjects in the light exercise condition jog for only 3 miles. Each subject engages
in one exercise level and one time of day, and the number of hours slept that night is
recorded. The following data are obtained:
