Here are summary statistics for randomly selected weights of newborn girls n= 227, x = 30.9 hg, s= 6.5hg. Construct a confidence interval estimate of the mean. Use a 90% confidence level. Are these results very different from the confidence interval 30.2 hg< u < 32.2 hg with only 16 sample values, x= 31.2 hg, and s=2.2 hg?
