VI. The following are low density lipoprotein (LDL) levels, measured in mg/dL in 20 subjects while on vegan diets who are participating in a study of risk factors for heart disease. The mean LDL in persons free of heart disease is reported to be 192. Researchers at the Cleveland Clinic hypothesize that the LDL in persons on a vegan diet will be lower. Using a 5% level of significance, is there evidence to support the researchers' hypothesis? 201 186 149 207 177 185 212 197 172 183 219 201 163 181 199 179 190 180 176 188 1.
