Using a response surface design, the fitted second order model of the form

3): 20 10ml + 10% + 103:3 23:? 73:3 537% + 411% M1933 2.932%, for the response g was obtained. a) Write down the matrix B for this model. b) Find the stationary point. c) Find the value :03 of the predicted respolnse at the stationary point. (:1) Find the eigenvalues of B. e) Write the model in the canonical form. What is the type of the stationary point? Can it be considered a ridge system
