The man decides to experiment. Each day he fips a coin to determine which way to go, driving each route 20 days. He finds that Route A takes an average of 44 minutes, with standard deviation 4 minutes and Route B takes an average of 49 minutes with standard deviation 1 minute. Histograms of travel times for the routes are roughly symmetric and show no outlers Complete parte a and b CHE a) Find a 6% confidence interval for the difference between the Route Band Route Acommuting times. (-) The confidence interval is (0) (Round to two decimal places as needed)
