An unreplicated 2 51 fractional factorial experiment with four center points has been run in a chemical process. The response variable is the molecular weight. The experimenter has used the following factors, Suppose that the prediction equation that results from this experiment is y = 10 + 3x1 + 2x2 x1x2. What is the predicted response at A = 30, B = 165, C = 50, D = 135, and E = 1.

3. [DAE 8.33] An unreplicated 25-1 fractional factorial experiment with four center points has been run in a chemical process. The response variable is molecular weight. The experimenter has used the following factors, Factor Natural Levels Coded Levels (x's) A - time 20, 40 (minutes) -1, 1 B - temperature 160, 180 (degrees C) -1, 1 C - concentration 30, 60 (percent) -1, 1 D - stirring rate 100, 150 (rpm) -1, 1 E - catalyst type 1, 2 (Type) -1, 1 Suppose that the prediction equation that results from this experiment is y = 10 + 3x1 + 212 - T142. What is the predicted response at A = 30, B = 165, C = 50, D = 135, and E = 1
