The distribution of blood cholesterol level in the population of young men aged 20 to 34 years is close to Normal with standard deviation ? = 45 milligrams per deciliter (mg/dL). You measure the blood cholesterol of 13 cross-country runners. The mean level is x = 174 mg/dL. Assume that ? is the same as in the general population. How large a sample is needed to cut the margin-of-error in half for a 90% confidence interval of the mean level ? among the cross-country runners?
