Here are summary statistics for randomly selected weights of newborn​ girls: n=230  x=27.6 ​hg, s=6.9 hg. Construct a confidence interval estimate of the mean. Use a 98​% confidence level. Are these results very different from the confidence interval 25.8 hg<μ<29.8 hg with only 14 sample​ values, x=27.8 ​hg, and s=2.8 ​hg? What is the confidence interval for the population mean μ​? enter your response here hg<μ
