A 23 fаctоriаl experiment with оnly оne replicаte (8 runs) has been run in a chemical process. The response variable is molecular weight. The engineer has used the following factors: Factor Natural levels Coded levels (x’s) A - time 80, 100 (minutes) -1, 1 B - temperature 150, 200 (deg C) -1, 1 C - concentration 30, 60 (percent) -1, 1 After conducting the experiment, the engineer computes the quantities in the following table (using coded units): Term Effect Estimate Sum of Squares % Contribution A X 32.00 X B 6.50 X 65.44 C 1.50 4.50 3.48 AB 0.75 1.125 3.86 AC -0.50 0.50 0.39 BC 1.50 4.50 3.48 ABC -1.00 2.00 1.55 Answer the following questions (15 – 19) about this experiment. Each question is worth 5 points.
