Safety considerations are important in the design of automobiles. The article “An Optimum Design Methodology Development Using a Statistical Technique for Vehicle Occupant Safety” (J. Hong, M. Mun, and S. Song, Proceedings of the Institution of Mechanical Engineers, 2001:795–801) presents results from an occupant simulation study. The outcome variable is chest acceleration (in g) 3 ms after impact. Four factors were considered. They were A: the airbag vent characteristic, B: the airbag inflator trigger time, C: the airbag inflator mass flow rate, and D: the stress–strain relationship of knee foam. The results (part of a larger study) are presented in the following table. There is one replicate per treatment.
a. Compute estimates of the main effects and the interactions.
b. If you were to design a follow-up study, which factor or factors would you focus on? Explain.
