The data in Table 14E.6 were collected by a chemical engineer. The response y is filtration time, x1 is temperature and x2 is pressure. Fit a second-order model.

(a) What operating conditions would you recommend if the objective is to minimize the filtration time?
(b) What operating conditions would you recommend if the objective is to operate the process at a mean filtration rate very close to 46?
