Fifteen adult males between the ages of 35 and 50 participated in a study to evaluate the effect ofdiet and exercise on blood cholesterol levels. The total cholesterol was measured in each subjectinitially and then three months after participating in an aerobic exercise program and switching toa low-fat diet. The data are shown in the following table:Blood Cholesterol LevelSubjectBeforeAfter1265229224023125822729524025123824524128723483142569260247102792391128324612240218132382191422522615247233Do the data support the claim that low-fat diet and aerobic exercise are of value in producing amean reduction in blood cholesterol levels?
