Here are summary statistics for randomly selected weights of newborn girls: n = 243; overline x =31.3 hg; s = 7.9 hg Construct a confidence interval estimate of the mean. Use a 95% confidence level. Are these results very different from the confidence interval 29.9hg < mu < 33.7 hg with only 15 sample values, overline x =31.8 hg, and s = 3.5 hg? What is the confidence interval for the population mean ?l
