Here are summary statistics for randomly selected weights of newborn girls: n=211,xˉ=31.8 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 28.7hg<μ<34.3hg with only 13 sample values, xˉ=31.5hg, and s=3.3hg ? What is the confidence interval for the population mean μ ? hg<μ<hg (Round to one decimal place as needed.)
