Question
A man who moves to a new oity sees that there are two routes he could take to work. A neighbor who has lived there a long time tells him Route A wil average 5 minutes faster than Route B. The man decides to experiment. Each day he flips a coin to determine which way to go, driving each route 15 days. He finds that Route A takes an average of 49 minutes, with standard deviation 3 minutes, and Route B takes an average of 54 minutes, with standard deviation 1 minute. Histograms of travel times for the routes are roughly symmetric and show no outlers Complete parts a and b. a) Find a 95% oonfidence Interval for the difference between the Route B and Route A commuting times. (Pn "PA) The confidence interval is D (Round to two decimal places as needed.)
