Here are summary statistics for randomly selected weights of newborn girls: n= 153, x= 32.2 hg, s= 7.6 hg. Construct a confidence interval estimate of the mean. Use a 90% confidence level. Are these results very different from the confidence interval 31.2 hg<x<34.2 hg with only 15 sample values, x= 32.7 hg, and s= 3.3 hg? What is the confidence interval for the population mean? hg<u< hg (Round to one decimal place as needed.) A food safety guideline is that...
