The table below is the output from the Analysis of Variance (ANOVA) from the DOE.

1. Identify the main effects and interactions that are significant at the 95% confidence level.
2. Was the Fractional Factorial DOE justified (that is, can 3-way and higher order terms be ignored)? Explain your answer.
3. Which factor has the greatest impact for increasing flight time? The least impact?
