Here are summary statistics for randomly selected weights of newborn​ girls: n=246​, x =27.1 ​hg, s=7.3 hg. Construct a confidence interval estimate of the mean. Use a 99​% confidence level. Are these results very different from the confidence interval 25.2 hg<μ<29.4 hg with only 19 sample​ values, x =27.3 hg, and s=3.23.2 ​hg?   What is the confidence interval for the population mean μ​?   _hg<μ<_hg
