Example 14.1 (page 360) described NHANES survey data on the body mass index (BMI) of 654 young women. The mean BMI in the sample was x¯¯¯ = 26.8. We treated these data as an SRS from a Normally distributed population with standard deviation σ = 7.5. (a) Give three confidence intervals for the mean BMI μ in this population, using 90%, 95%, and 99% confidence. (b) What are the margins of error for 90%, 95%, and 99% confidence? How does increasing the confidence level change the margin of error of a confidence interval when the sample size and population standard deviation remain the same?
