Here are summary statistics for randomly selected weights of newborn girls: n = 177, x= 33.2 hg, s = 7.9 hg. Construct a confidence interval estimate of the mean. Use a 98% confidence level. Are these results very different from the confidence interval 31.0 hg <u< 35.8 hg with only 15 sample values, x = 33.4 hg, and s= 3.6 hg? What is the confidence interval for the population mean u? hg <μς ng (Round to one decimal place as needed.)
