Here are summary statistics for randomly selected weights of newborn girls: n equals = 173, x overbar equals 32.2 hg, s 7.6 hg. Construct a confidence interval estimate of the mean. Use a 99% confidence level. Are these results very different from the confidence interval 29.4 hg less than < mμ less than < 34.4 hg with only 16 sample values, x overbar equals = 31.9 hg, and s 3.4 hg? What is the confidence interval for the population mean...
