Here are summary statistics for randomly selected weights of newborn​ girls: n=244, x=31.8 hg, s=7.3hg. Construct a confidence interval estimate of the mean. Use a 99% confidence level. Are these results very different from the confidence interval 29.8 hg < mean < 34.0 hg with only 16 sample values, x= 31.9 hg, and s= 2.9 hg? What is the confidence interval for the population mean ?
