Here are summary statistics for randomly selected weights of newborn girls: n = 224, x= 28.1 hg, s= 7.9 hg. Construct a confidence interval estimate of the mean. Us a 95% confidence level. Are these results very different from the confidence interval 26.5 hg <<30.7 hg with only 14 sample values, x= 28.6 hg, and s= 3.7 hg? What is the confidence interval for the population mean μ? hg<< hg (Round to one decimal place as needed.)'
