Here are summary statistics for randomly selected weights of newborn girls: n=241, x=29.6 hg, s=6.9 hg. Construct a confidence interval estimate of the mean. Use a 98% confidence level. Are these results very different from the confidence interval 28.0 hg<μ<31.8 hg with only 13 sample values, x=29.9 hg, and s=2.6 hg?
