Cholesterol: An article in the Archives of Internal Medicine reported that in a sample of 244 men
Cholesterol: An article in the Archives of Internal Medicine reported that in a sample of 244 men, 73 had elevated total cholesterol levels (more than 200 milligrams per deciliter). In a sample of 234 women, 44 had elevated cholesterol levels. Can you conclude that the proportion of men with elevated cholesterol levels is greater than the proportion of women? Let P1 denote the proportion of men with elevated cholesterol levels and let P2 denote the cholesterol levels for the controls....

Testing blood cholesterol. The distribution of blood cholesterol level in the popnudation of young men aged 20 to 34 years is close to Nonal with mean 188 milligrams per deciliter (mg/dL) and standard deviation 41 mg/dL. You measure the blood cholesterol of 14 young men aged 20 to 34 years who have completed at least one marathon. The mean level is x = 172 mg/dL. Assume that σ is the same as in the general population. Use this information to...
