An experiment was performed to improve the yield of a chemical process. Four factors were selected, and two replicates of a completely randomized experiment were run. The results are shown in the following table: A B C D Yield 1 -1 -1 -1 -1 95 2 -1 -1 -1 -1 93 3 1 -1 -1 -1 74 4 1 -1 -1 -1 78 5 -1 1 -1 -1 81 6 -1 1 -1 -1 85 7 1 1 -1 -1...

A 2^4-1  experiment was performed to improve the yield of a chemical process. Four factors were selected, and two replicates were run. Due to raw materials constraints, it was possible to run only 8 runs. Thus, the design generator D = ABC was selected. The data are shown in the following table. Create the standard order fractional factorial design in Minitab. Analyze the fractional factorial design and, following the principle of hierarchical order, remove all interaction terms then main effects that...

Yield of Chemical Process Two catalysts were analyzed to determine how they affect the mean yield of chemical process. Specifically, catalyst 1 is currently used; but catalyst 2 is acceptable. Because catalyst 2 is cheaper, it should be adopted, if it does not change the process yield. Two tests were run in the pilot plant. Eight samples of each type of catalyst were randomly and independently selected from the pilot plant, and the chemical process yield were recorded. The data...
