Here are summary statistics for randomly selected weights of newborn​ girls: n = 160​, x = 30.7 ​hg, s = 6.6 hg. Construct a confidence interval estimate of the mean. Use a 99​% confidence level. Are these results very different from the confidence interval 29.4 hg < u < 32.4 hg with only 17 sample​ values, x = 30.9 ​hg, and s = 2.1 ​hg?
