Here are summary statistics for randomly selected weights of newborn girls: n= 159, x = 32.4 hg, s= 6.9 hg. Construct a confidence interval estimate of the mean. Use a 95% confidence level. Are these results very different from the confidence interval 31.0 hg <μ<33.4 hg with only 19 sample values, x= 32.2 hg, and s=2.5 hg? What is the confidence interval for the population mean µ? |hg<μ
