The research model for this fictitious study is: U.S. Navy carrier air wing pilots that exercise 60 minutes 5 times a week shows fewer symptoms of fatigue will on missions than U.S. Navy carrier air wing pilots that do not exercise while deployed on the aircraft carrier. The hypotheses to be tested in this study are. Null Hypothesis: There is no significant difference in fatigue symptoms of U.S. Navy carrier air wing pilots who exercise 60 minutes 5 times a week, then U.S. Navy carrier air wing pilots who do not exercise while deployed on the aircraft carrier. Alternative Hypothesis: U.S. Navy carrier pilots who exercise 60 minutes 5 times a week shows fewer symptoms of fatigue then U.S. Navy carrier air wing pilots who do not exercise while deployed on the aircraft carrier. Fifty pilots from different carrier air wing strike groups responded to this questionair anomously by leaving their completed questionair at each of their squadron's safety office. This questionair contained 3 variables to use to generate the data. The variables interested under this fictitious study are: 1. Often did you exercise during the week on deployment, 2. Long per exercise session, 3. Feel less fatigue during the mission when you included exercise into your routine. In order to discover if exercising 60 minutes, 5 times a week helps eliminate the symptoms of fatigue during the mission. pilots 1 2 3 4 5 6 7 8 9 10 11 12 13 1 5 5 6 5 4 5 3 3 2 4 5 5 4 2 60 60 30 60 20 60 40 50 40 40 60 60 20 3 Y Y Y Y N Y Y Y N Y Y Y N 14 15 16 17 18 19 20 21 22 23 24 25 26 3 6 5 5 4 7 3 2 5 5 3 4 5 40 30 60 60 30 20 50 10 60 60 30 30 60 Y Y Y Y N N N Y Y Y N N Y 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 5 4 5 5 3 6 2 2 4 5 0 0 0 3 5 4 5 2 5 3 4 5 5 1 60 30 60 60 20 10 30 40 50 60 0 0 0 20 60 60 60 10 60 20 30 40 60 15 Y N Y Y Y Y N Y Y Y N N N N Y Y Y N Y N N Y Y N Hypothesis test: Independent Groups (t-test, unequal variance) Group 1 3.92 Group 2 39.90 mean 1.60 50 20.01 50 Std dev n 49 df -35.980 difference (group 1 - Group 2) 2.839 standard error of difference 0 hypothesized difference -12.67 t 2.2E-17 p-value (one-tailed, lower)
