Question 2: (CLO 3, PLO 2) (25) The effect of five different ingredients (V, W, X, Y, Z) on reaction time of a chemical process is being studied. Each batch of new raw material is only large enough to permit five runs to be made. Furthermore, each run requires approximately 2 hours, so that only five (05) runs can be made in a day. The experimenter decides to run the experiment as a Latin square design so that the days effect and batch effects can be systematically controlled. The data is obtained from experiment as follows Day Batch 2 3 4 5 A=8 B-7 D=1 C=7 E=5 C-11 E 2 A-7 D 3 B-8 AWN B-4 A=9 C=11 E=1 D6 D=6 C=8 E=8 B=6 A=10 E=4 D=2 B=5 A=8 C=8 Analyze the data at a = 0.05, identify significant factors and draw conclusions
