Here are summary statistics for randomly selected weights of newborn​ girls: n=201​, x=28.4 ​hg, s=6.2 hg. Construct a confidence interval estimate of the mean. Use a 98​% confidence level. Are these results very different from the confidence interval 27.3 hg<μ<29.9 hg with only 13 sample​ values, x=28.6 ​hg, and s=1.8 ​hg? What is the confidence interval for the population mean μ​?
