Example 14.1 (page 352) 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 ? = 7.5. Suppose that we had an SRS of just 100 young women. What would be the margin of error for 95% confidence? A. 0.75 B. 1.47 C. 1.54 D. 1.23 Solution B. 1.47.
