Which are significant? A. A professor in physical education conducts an experiment to compare the effects onnighttime sleep of different amounts of exercise and the time of day when the exercise isdone. 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 arerandomly assigned to the six cells such that there are 6 subjects per cell. The subjectswho 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 engagesin one exercise level and one time of day, and the number of hours slept that night isrecorded. The following data are obtained:ExerciseTime of DayLightModerateHeavyMorning6.57.47.4 7.38.0 7.67.36.67.26.86.86.77.67.47.7 6.67.1 7.2Evening7.17.98.27.77.48.08.28.77.57.68.18.59.69.5 9.47.68.2 8.0192ONCON- 00
