We have the survey data on the body mass index (BMI) of 665 young women. The mean BMI in the sample was x = 26.2.

We treated these data as an SRS from a Normally distributed population with standard deviation σ = 8.4.

Give confidence intervals for the mean BMI and the margins of error for 90%, 95%, and 99% confidence. (Round your answers to two decimal places.) also include margin errors for each confidence interval.

and 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?
