Question:

The hexagon design that follows is used in an experiment that has the objective of fitting a second-order model:

X1 X2 y 1 68 V0.75 V0.75 0.5 74 -0.5 65 -1 60 -V0.75 -V0.75 -0.5 63 0.5 70 58 60 57 55 69

(a) Fit the second-order model.

(b) Perform the canonical analysis. What type of surface has been found?

(d) Where would you run this process if the objective is to obtain a response that is as close to 65 as possible?
