![Here are summary statistics for randomly selected weights of newborn girls: n = 194, x 30.5 hg, s= 6.8 hg. Construct a confidence interval estimate of the mean.
Use a 98% confidence level. Are these results very different from the confidence interval 29.2 hg <p<32.4 hg with only 18 sample values, x= 30.8 hg, and
s=2.7 hg?
