An NHANES report gives data for 936 men aged 20-29 years. The mean BMI of these 8936 men was 27.2kg/m2. We have treated these data as an SRS from normally distributed population with standard deviation = 11.6.

Suppose that we had an SRS of just 100 young men. What would be the margin of error for 95% confidence?
