shows the moisture content of the eight replications for each of the nine experiments in the inner array. The coded target value is 20.

Show the complete parameter design layout using the Taguchi method. Calculate the mean response and the appropriate signal-to-noise ratios. Plot the average S/N ratios and the average responses and discuss how the design factor levels are to be selected. Use the average response plots to determine the existence of the interaction effects A× E, B × F, E × F, and E × G. What are the optimal settings of the design parameters using Taguchi’s parameter design approach?
