Here are summary statistics for randomly selected weights of newborn girls: n=210,xˉ=27.3hg,s=7.4hg. Construct a confidence interval estimate of the mean. Use a 90% confidence level. Are these results very different from the confidence interval 26.2hg<μ<28.6 hg with only 20 sample values, xˉ=27.4hg, and s=3.1hg ? What is the confidence interval for the population mean μ ? hg<μ<hg (Round to one decimal place as needed.)
