Here are summary statistics for randomly selected weights of
newborn girls: n=224, x=28.3 hg, s=6.3 hg. Construct a
confidence interval estimate of the mean. Use a 90% confidence
level. Are these results very different from the confidence
interval 28.1 hg<μ<29.7 hg with only 17 sample values,
x=28.9 hg, and s=1.9 hg?
What is the confidence interval for the population mean μ?
Are the results between the two confidence intervals very
different?
