Here are summary statistics for randomly selected weights of newborn girls: n= 231, x= 31.1 hg, s = 6.5 hg. Construct a confidence interval estimate of the mean. Use a 99% confidence level. Are these results very different from the confidence %3D interval 29.9 hg <µ< 33.5 hg with only 13 sample values, x = 31.7 hg, and s = 2.1 hg? What is the confidence interval for the population mean µ? hg < µ< hg (Round to one decimal place as needed.)
