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?
