Do plastic grocery bags from Target or plastic bags from Publix hold more weight? A group of AP students decided to investigate by filling a random sample of 5 bags from each store with common grocery items until the bags ripped. Then they weighed the contents of items in each bag to determine its capacity. Here are the results, in grams: Target 12,572 13,999 11,215 15,447 10,896 Publix 9552 10.896 6983 8767 9972 Assuming the population of both follow a normal distribution, construct a 99% confidence interval for the difference in mean capacity of plastic grocery bags from Target and Publix. Calculate and interpret the confidence interval using the calculator: We are, Confident that the difference in capacity of plastic grocery bags from Target and Publix is in the interval between and ! 1 99 :: real true : 6110.41 95 :: mean propotion : 90 :: -100.946 :: 7284.55 :: 1073.19What is the critical value from the previous question?
