Here are summary statistics for randomly selected weights of newborn​ girls: n=242​, x=28.7 ​hg, s=7.9 hg. Construct a confidence interval estimate of the mean. Use a 99​% confidence level. Are these results very different from the confidence interval 25.8 hg<μ<30.8 hg with only 18 sample​ values, x=28.3 ​hg, and s=3.7 ​hg? What is the confidence interval for the population mean μ​?   nothing hg<μ
