Researchers at Purdue University and Wichita State University found that airlines are doing a better job of getting passengers to their destinations on time. AirTran Airways and Southwest Airlines were among the leaders in on-time arrivals with both having 88% of their flights arriving on time. But for the 12% of flights that were delayed, how many minutes were these flights late? Sample data showing the number of minutes that delayed flights were late are provided in the Excel Online file below. Data are shown for both airlines. Construct a spreadsheet to answer the following questions. Open spreadsheet AirTran Southwest 40 100 58 69 62 38 104 40 56 42 6 53 3 80 88 89 112 70 34 66 116 65 89 50 71 32 72 34 4 26 67 47 41 59 35 34 68 93 20 78 85 120 3 47 79 b. What is the sample mean number of minutes late for delayed flights for each of these two airlines? AirTran (to 2 decimals) Southwest (to 2 decimals) b. What is the sample mean number of minutes late for delayed flights for each of these two airlines? AirTran (to 2 decimals) Southwest (to 2 decimals) c. Using a .05 level of significance, what is the p-value, and what is your conclusion? p-value is (to 4 decimals)
