please i beg you Solve Exercise 8.50Please provide typed answers. 8.49 Confidence intervals and football wins: In anleagues within FCS, the Patriot League, played 4that weekend. Their mean was 8.75.gamesexercise in Chapter 7. we asked whether college foot-ball teams tend to be more likely or less likely to bemismatched in the upper National Collegiate AthleticAssociation (NCAA) divisions. During one week ofa college football season, the population of 53 Toot-ball Bowl Subdivision (FBS) games had a mean spread(winning score minus losing score) of 16.189, with astandard deviation of 12.128. We took a sample of 4games that were played that week in the next-highestleague, the Football Championship Subdivision (FCS),to see if the spread were different: one of the manya. Calculate the 95% confidence interval for this sample.b. State in your own words what we learn from thisconfidence interval.c. What information does the confidence intervalgive us that we also get from a hypothesis test?d. What additional information does the confidenceinterval give us that we do not get from a hypoth-esis test?8.50 Confidence intervals and football wins (contin-ued): Using the football data presented in Exercise8.49, practice evaluating data using confidence ntervals.a. Compute the 80% confidence interval,b How do the conclusion and the confidence intervalchange as you move from 95% confidence to 80%confidence?C.Why don't we talk about having 100% confidence?

Bulletproof Vests. In the article “A Common Police Vest Fails the Bulletproof Test,” E. Lichtblau reported on a U.S. Department of Justice study of 103 bulletproof vests containing a fiber known as Zylon. In ballistics tests, only 4 of these vests produced acceptable safety outcomes (and resulted in immediate changes in federal safety guidelines). Find a 95% confidence interval for the proportion of all such vests that would produce acceptable safety outcomes by using the a. one-proportion z-interval procedure. b. one-proportion plus-four z-interval procedure. (See page 556 for the details of this procedure.) c. Explain the large discrepancy between the two methods. d. Which confidence interval would you use? Explain your answer.
