Here are summary statistics for randomly selected weights of newborn girls: n= 151, x=27.6 hg, s= 6.1 hg. Construct a confidence interval estimate of the mean. Use a 99% confidence level. Are these results very different from the confidence interval 26.8 hg <μ<29.4 hg with only 14 sample values, x = 28.1 hg, and s= 1.6 hg? What is the confidence interval for the population mean μ? |hg<μ<[ hg (Round to one decimal place as needed.)
