Listed below are measured amounts of caffeine (mg per 12 oz of drink) obtained in one can from each of 20 brands. Using the bootstrap method with 1000 bootstrap samples, construct a 99% confidence interval estimate of m. How does the result compare to the confidence interval found in Exercise 22 “Caffeine in Soft Drinks” in Section 7-2 on page 330?

Data From Exercise 22 Section 7-2:

Listed below are measured amounts of caffeine (mg per 12 oz of drink) obtained in one can from each of 20 brands (7UP, A&W Root Beer, Cherry Coke, . . . , TaB). Use a confidence level of 99%. Does the confidence interval give us good information about the population of all cans of the same 20 brands that are consumed? Does the sample appear to be from a normally distributed population? If not, how are the results affected?
