Here are summary statistics for randomly selected weights of newborn girls: n=227, x=28.7 hg, s=7.3 hg. Construct a confidence interval estimate of the mean. Use a 90% confidence level. Are these results very different from the confidence interval 27.7 hg<<30.1 hg with only 20 sample values, x=28.9 hg. and s=3.1 hg? What is the confidence interval for the population mean u? ng<<ho (Round to one decimal place as needed.) GILE
