Here are summary statistics for randomly selected weights of newborn girls: n= 223, x = 26.6 hg, s = 6.5 hg. Construct a confidence interval estimate of the mean. Use a 95% confidence level. Are these results very different from the confidence interval 24.7 hg <u< 27.7 hg with only 12 sample values, x = 26.2 hg, ands 2.3 hg? What is the confidence interval for the population mean u? hg <u< hg (Round to one decimal place as needed.)
