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...

A researcher collected sample data for 14 women ages 18 to 24. The sample had a mean serum cholesterol level (measured in mg/100 mL) of 188.1, with a standard deviation of 6.8. Assuming that serum cholesterol levels for women ages 18 to 24 are normally distributed, find a 95% confidence interval for the mean serum cholesterol level of all women in this age group. Then complete the table below. Carry your intermediate computations to at least three decimal places. Round...
