10. The Table 11.13 below shows the results of Chau and Kelly (1993) mixture process variable experiments (MPV) with printable coating material, which were described in Section 11.7.

(a) Create this design and merge the response values.

(b) Fit a simplied model of the form of Equation (11.28) with only one process variable z.

(c) Does the process variable thickness aect the opacity?

(d) Make a contour plot over constrained mixture space holding the process variable thickness constant at is midpoint (i.e., coded value z=0).

(e) Can you identify a region where predicted opacity > 0:86?
