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...

Student stress at final exam time comes partly from the
uncertainty of grades and the consequences of those grades. Can
knowledge of a midterm grade be used to predict a final exam grade?
A random sample of 200 BCOM students from recent years was taken
and their percentage grades on assignments, midterm exam, and final
exam were recorded. Let’s examine the ability of midterm and
assignment grades to predict final exam grades.
