Here are summary statistics for randomly selected weights of newborn​ girls: n=204, x=26.9 ​hg, s=6.9 hg. Construct a confidence interval estimate of the mean. Use a 90​% confidence level. Are these results very different from the confidence interval 26.0 hg< μ <28.4 hg with only 14 sample​ values, x =27.2 ​hg, and s=2.6 ​hg?
