FALL 2022 % Qgtstion 7: The mean throwing distance of a football for Marco, a high school freshman quarterback, is 45 yards, with a standard deviation of three yards. The team coach tells Marco to adjust his grip to get more distance. The coach records the distances for 25 throws. For the 25 throws, Marco's mean distance was 50 yards. The coach thought the different grip helped Marco throw farther than 45 yards. Conduct a hypothesis test using o 5%. Assume the throw distances for footballs are normal. First, determine what type of test this is, set up the hypothesis test, find the pvalue, sketch the graph, compare the pvalue and a, and state your decision 5 conclusion.
