Question

Here are summary statistics for randomly selected weights of newborn girls: n=152, x =29.4 hg, s=7.1 hg. Construct a confidence interval estimate of the mean. Use a 90% confidence level. Are these results very different from the confidence interval 27.9 hg <μ<30.3 hg with only 19 sample values, x =29.1 hg, and s=2.9 hg?

What is the confidence interval for the population mean μ?

_ hg <μ< _ hg
