Here are summary statistics for randomly selected weights of newborn​ girls: n =187​, x = 26.4 ​hg, s = 6.4 hg. Construct a confidence interval estimate of the mean. Use a 99​% confidence level. Are these results very different from the confidence interval 25.0hg <u<28.8 hg with only 13 sample​ values, x = 26.9 ​hg, and s = 2.2 ​hg?

Are the results between the two confidence intervals very​ different?

A.​No, because the confidence interval limits are similar.
