A 23 factorial experiment with only two replicates (16 runs) has been run in a chemical process. The response variable is molecular weight. The engineer has used the following factors with their natural low and high levels as shown: A (40, 80), B(100, 130), and C(25, 75). After conducting the experiment, the engineer computes the quantities in the following table (using coded units): Term Effect Estimate Sum of Squares % Contribution A 4.50 81.00 19.95 B 6.00 144.00 X C X 16.00 3.94 AB 5.00 100.00 24.63 AC 3.00 36.00 8.87 BC 2.50 X 6.16 ABC 1.00 4.00 0.99 Answer the following questions (1 – 5) about this experiment. Each question is worth 8 points. Please select the correct answer.
