2. Consider the familial aggregation of cholesterol levels. Suppose cholesterol levels are assessed in 100 children, 2 to 14 years old, of men who have died from heart disease and it is found that the mean cholesterol level in the group is 207.3 mg/dL and the sample standard deviation is 35.6 mg/dL. A group of 74 control children whose fathers are alive and do not have heart disease is selected. The mean cholesterol level of the control children is 193.4 with a sample standard deviation of 17.3 mg/dL. Test for the equality of the mean cholesterol levels of the children whose fathers have died from heart disease versus the children whose fathers do not have a history of heart disease.
