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 2 points with 99% confidence assuming s=19.4 based on earlier studies? Suppose the doctor would be content with 95% confidence. How does the decrease in confidence affec the sample size required? How does the decrease in confidence affect the sample size required? A. The sample size is the same for all levels of confidence. B. Decreasing the confidence level decreases the sample size needed. C. Decreasing the confidence level increases the sample size needed
