8. 15 adult males between the ages of 35 and 50 participated in a study to evaluate the effect of diet and exercise on blood cholesterol levels. The total cholesterol was measured in each subject initially and then three months after participating in an aerobic exercise program and switching to a low-fat diet. The data are shown in the following table. Blood Cholesterol Level Subject Before After 1 265 229 2 240 231...

The following table contains cholesterol levels collected from
non-smoking males. The before cholesterol level is before they
exercised, and the after cholesterol level was taken after the same
subject regularly exercised for two months. It is claimed that the
mean cholesterol level before exercise is greater than that after
exercise. Assume that the population of cholesterol level
difference (before-after) is normally distributed. Test the claim
at the 0.01 level.
