Question:

An experimenter has run a Box-Behnken design and has obtained the results below, where the response variable is the viscosity of a polymer:

Agitation Rate Level Temp. Pressure X2 X3 High 200 10.0 25 +1 +1 +1 Middle 175 7.5 20 Low 150 5.0 15 -1 -1 -1

(a) Fit the second-order model.

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

(d) What operating conditions would you recommend if it is important to obtain a viscosity that is as close to 600 as possible?
