Independent Sample t Test: Mean visiting time

In a study by Web Criteria, it took an average of 2.1 minutes to locate information and buy products on the Delta Airlines website, compared to an average of 2.7 minutes on the British Airways site. Assume that data file XR11012 contains the times (in minutes) required during visits to the two websites. In a suitable one-tail test at the 0.01 level, was the mean time for the Delta visits significantly less than that for the British Airway visits? Identify and interpret the p-value for the test.
