An NHANES report gives data for 647 women aged 20–29 years. The BMI of these 647 women was x= 25.8. On thebasis of this sample, we want to estimate the BMI u in the population of all 20.6 million women in this age group. Wetreated these data as an SRS from a Normally distributed population with standard deviation o = 7.1.(a) Give three confidence intervals for the mcan BMI u in this population, using 90%, 95%, and 99% confidence.Enter the lower and upper bound for the 90% confidence interval. (Enter your answers rounded to two decimal places. Ifyou are using Crunchlt, adjust the default precision under Preferences as necessary.
