Here are summary statistics for randomly selected weights of newborn girls: n=181, x= 33.2 hg, s=7.3 hg. Construct a confidence interval estimate of the mean. Use a 98% confidence level. Are these results very different from the confidence interval 30.9 hg<μ<34.5 hg with only 18 sample values, x= 32.7 hg, and s=2.9 hg? What is the confidence interval for the population mean μ? hg<μ
