shows the moisture content in a coded scale for four replications of each of the nine experiments in the inner array. It is preferable that the moisture content be around a coded value of 20.

Show the complete parameter design layout using the Taguchi method. Calculate the mean response and the appropriate signal-to-noise ratio. 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 possible interactionsB×

E and C× F. What are the optimal settings of the design parameters using Taguchi’s parameter design approach?
