wants to know if it is better for Instructor Pilots to give flight students feedback in the airplane immediately after each maneuver rather than to wait till they are on the ground and debriefing. Six student pilots are selected. Each student receives immediate feedback on half of their flights and receives delayed (after landing) feedback on the other half of their flights. Average scores for the student’s evaluations are listed in the table below. Show work. Student Pilot Score for Immediate Feedback Score for Feedback Received After on the Ground Student Pilot A 4 2 Student Pilot B 3 4 Student Pilot C 5 2 Student Pilot D 3 3 Student Pilot E 5 3 Student Pilot F 5 2 a. Test the hypothesis that the student pilots receive higher evaluations on flights where they received immediate feedback compared to delayed (after landing) feedback. Use α =.05. Use the four steps of hypothesis testing. b. Calculate Omega squared (ώ2)
