TABLE 11.15
Results of a Two-Factor Display Panel Experiment
a. Interpret the MINITAB interaction plot in Figure 11.14. Then test for interaction with a = .05.
b. Test the significance of display panel effects with α = .05.
c. Test the significance of emergency condition effects with α = .05.
d. Make pairwise comparisons of display panels A, B, and C by using Tukey simultaneous 95 percent confidence intervals.
e. Make pairwise comparisons of emergency conditions 1, 2, 3, and 4 by using Tukey simultaneous 95 percent confidence intervals.
f. Which display panel minimizes the time required to stabilize an emergency condition? Does your answer depend on the emergency condition? Why?
g. Calculate a 95 percent (individual) confidence interval for the mean time required to stabilize emergency condition 4 using display panel B.
