2. A study compared three different display panels for use by air traffic controllers. Each display panel was tested in a simulated emergency condition; 12 highly trained air traffic controllers took part in the study. Four controllers were randomly assigned to each display panel. The time (in seconds) needed to stabilize the emergency condition was recorded. The results of the study are given below. A 20 27 24 25 Display Panel B 25 22 18 19 Show all your work and circle your final answers. C 39 35 34 32 Can we conclude that display panels A, B, and C have different effects on the mean time to stabilize the emergency condition? Fit an appropriate linear model to the data and test at the 0.01 level of significance. Provide conclusion in the context of this problem.
