A chemical lab studies the effect of three factors in a process yield. The Question 2 three factors are: temperature with two levels (160 ad 180 F), chemical concentration (20 and 40%), and two catalysts (A and B). The following table summarizes the results of the experiments. Experiment Temperature Concentration | Catalyst Yield 60 1 -1 -1 -1 72 2 1 -1 -1 54 3 -1 1 -1 68 4 1 1 -1 52 5 -1 -1 1 83 1 -1 1 45 7 -1 1 1 80 8. 1 1 a) What is the average effect of the concentration? b) Does the Catalyst type have an effect on the yield? c) Do Temperature and Catalyst type interact?
