Here are summary statistics for randomly selected weights of newborn girls: n = 167, x= 30.6 hg, s= 6.2 hg. Construct a confidence interval estimate of the mean. Use a 99% confidence level. Are these results very different from the confidence
interval 29.2 hg <<32.2 hg with only 13 sample values, x= 30.7 hg, and s= 1.8 hg?
What is the confidence interval for the population mean µ?
hg<u<hg (Round to one decimal place as needed.)
