Question
Transcribed Image Text:A study compared three display panels used by air traffic controllers. Each display panel was tested for four different simulated emergency conditions. Twenty-four highly trained air traffic controllers were used in the study. Two controllers were randomly assigned to each display panel—emergency condition combination. The time (in seconds) required to stabilize the emergency condition was recorded. The following table gives the resulting data and the JMP output of a two-way ANOVA of the data.
### Data Table
#### Emergency Condition
| Display Panel | 1 | 2 | 3 | 4 |
|---------------|----|----|----|----|
| A | 17 | 21 | 34 | 14 |
| A | 16 | 23 | 31 | 19 |
| B | 29 | 32 | 28 | 27 |
| B | 23 | 19 | 30 | 25 |
| C | 27 | 29 | 37 | 19 |
| C | 22 | 32 | 33 | 20 |
### Least Squares Means Estimates
- **Panel Estimate Condition Estimate:**
- A: 21.625000, 17.166667
- B: 25.125000, 24.166667
- C: 25.625000, 32.166667
- 33.333333
