Refer to the 23 dye process example in Chap. 4. Four additional tests were made at a midlevel oxidation temperature and oven pressure.

Two of the runs were done with Material Quality A, and two of runs were done with Material Quality B. The following results were obtained:

Reanalyze this example using the additional four runs. Plot the new runs on the cube. Estimate the nonlinear effect. Is the effect important relative to the factor effects? Plot the midlevel points on the response plots.
