Fifteen 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 229 1 265 2 240 3 258 4 295 5 251 6 245 7 11 287 8 314 231 227 240 238 241 234 256 247 239 246 218 219 226 233 9 260 10 279 11 283 12 240 13 238 14 225 15 247 Do the data support the claim that low-fat diet and aerobic exercise are of value in producing a mean reduction in blood cholesterol levels? Use a = 0.05
