He finds that Route A takes an average of 43 minutes, with standard deviation 2 minutes, and Route B takes an average of 47 minutes, with standard deviation 4 minutes. Histograms of travel times for the routes are roughly symmetric and show no outliers. Complete parts a and b. . . . . . a) Find a 95% confidence interval for the difference between the Route B and Route A commuting times, (HB - HA) The confidence interval is (). mi (Round to two decimal places as needed.)
