An NHANES report gives data for 654 men aged 20-29 years. The BMI of these 654 men was =25.1. On the basis of this sample, we want to estimate the BMI in the population of all 23.2 million American men in this age group. Treat these data as an SRS from a Normally distributed population with standard deviation=7.2.

Find the margins of error for 90% confidence based on SRSs of 415 young men and 1617 young men. Give your answers to four decimalplaces.
