Here are summary statistics for randomly selected weights of newborn girls: n = 152, x= 33.5 hg, s= 7.7 hg. Construct a confidence interval estimate of the mean. Use a 98% confidence level. Are
these results very different from the confidence interval 31.7 hg <μ<35.9 hg with only 18 sample values, x= 33.8 hg, and s= 3.5 hg?
What is the confidence interval for the population mean μ?
hg<μ< hg (Round to one decimal place as needed.)
