A doctor wants to estimate the mean HDL cholesterol of all 20- to 29-year-old females. How many subjects are needed to estimate the mean HDL cholesterol within 4 points with 99% confidence assuming s=15.1 based on earlier studies? Suppose the doctor would be content with 90% confidence. Question content area bottom Part 1 A 99% confidence level requires (Round up to the nearest subject.) Part 2 A 90% confidence level requires (Round up to the nearest subject.) Part 3 How does the decrease in confidence affect the sample size required?
