Question

An article on the qualification test program for a small rocket engine presents data from an experiment to assess the effects of vibration (A and B), temperature cycling (A and B), and altitude cycling (A and B) on thrust duration. Here is the JMP output. Use significance level 0.05 for all hypothesis tests. Assume all conditions are met.
