Here are summary statistics for randomly selected weights of newborn girls: n=152, x=33.5 hg, s=7.7 hg. Construct a confidence interval estimate of the mean. Use a 99% confidence level. Are these results very different from the confidence interval 30.5 hg<<35.7 hg with only 17 sample values, x=33.1 hg, and s=3.6 hg?

___hg < < ___hg (Round to one decimal place.)
