An nhanes report gives data for 652 women aged 20 – 29 20–29 years. the bmi of these 652 652 women was ¯ x = 26.5 x¯= 26.5 . on the basis of this sample, we want to estimate the bmi μ μ in the population of all 20.6 20.6 million women in this age group. we treated these data as an srs from a normally distributed population with standard deviation σ = 7.2 σ=7.2 . give three confidence intervals for the mean bmi μ in this population, using 90%, 95%, and 99% confidence. enter the lower and upper bound for the 90% confidence interval.

Lower bound of 90% confidence interval: 26.04

Upper bound of 90% confidence interval: 26.96

Step-by-step explanation:

We are given the following in the question:  

Sample mean, = 26.5

Sample size, n = 652

Population standard deviation, σ = 7.2

90% Confidence interval:

Putting the values, we get,
