Question #64 Factorial Regression: EngWear versus Blocks, . . . Temp Shown are the results of the engine manufacturer's factorial experiment to test the effect of oil viscosity and Coded Coefficients exhaust temperature on engine wear. The design was Term Effect Cool SE Coef T-Value P-Value VIF blocked by engine to mitigate any differences due to the Constant 3.BB75 0.0076 30.87 0.000 engines themselves. With an a of 0.05, what can we Blocks 1 -0.0375 0.0976 -0.39 0.708 1.00 conclude from these results? Viscosity 1.1750 0.5875 0.0076 0.000 1.00 Temp -0.9210 -0.4625 -4.74 0.DO0 1.00 A) The mean engine-wear values for the two engines are significantly different. B) The mean engine-wear values for the two engines are not significantly different. C) Exhaust temperature did not have a significant effect on engine wear. D) Viscosity did not have a significant effect on engine wear
