A metal casting process for the production of turbine blades was studied. Three factors were varied. They were A: the temperature of the metal, B: the temperature of the mold, and C: the pour speed. The outcome was the thickness of the blades, in mm. The results are presented in the following table. Thickness 4.61 B -1 -1 -1 -1 -1 4.51 -1 -1 4.60 -1 4.54 -1 4.61 4.61 -1 4.48 4.51 a. Compute estimates of the main effects and the interactions. b. Is it possible to compute an error sum of squares? Explain. Plot the estimates on a normal probability plot. Does the plot show that some of the factors influence the thickness? Éxplain. C.
