Here are summary statistics for randomly selected weights of newborn girls:

n=170, x=28. hg, s=6.2hg. Construct a confidence interval estimate of the mean. Use a 99%

confidence level. Are these results very different from the confidence interval 27.5 hg<<30.3 hg with only 14

sample values, x=28.9 hg, and s=1.8 hg?

What is the confidence interval for the population mean ?
