Solve this problem By minitab program 4.22. The effect of five different ingredients (A, B, C, D, E) on the reaction time of a chemical process is being studied. Each batch of new material is only large enough to permit five runs to be made. Furthermore, each run requires approximately 1 hours, so only five runs can be made in one day. The exper- imenter decides to run the experiment as a Latin square so that day and batch effects may be systematically controlled. She obtains the data that follow. Analyze the data from this exper- iment (use a = 0.05) and draw conclusions.
