A 23 fаctоriаl experiment with оnly twо replicаtes (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 35.47 C 2.00 16.00 3.94 AB 5.00 100.00 24.63 AC 3.00 36.00 8.87 BC 2.50 25.00 6.16 ABC 1.00 4.00 0.99 Answer the following questions (1 – 5) about this experiment. Each question is worth 10 points. Please circle the correct answer. The effect estimate for the C main effect is [effect] The sum of squares for BC interaction is [squares] The percent contribution for the main effect of factor B is [contribution]' Suppose that the experimenter uses ONLY the sums of squares for all 4 of the interaction terms as an estimate of an error sum of squares. Note, to make the problem a bit easier, we are NOT including the pure error sums of squares, so you do NOT need to estimate this from the table or include the corresponding degrees of freedom for the pure error. The error mean square would then be [error] Suppose that the average of all 16 responses is 150, and you use a model containing only the A and B main effects and the AB interaction. The predicted response at the point A = 65 and B = 125 is [predicted]
