(8 pts) 8. The region of experimentation for three factors are: time (40

(S pts) S. The region Of experimentation for three factors are: time (40 S t S 80min), temperature (200 S T 30000), and pressure (20 p 50psi). A first-order model in coded Variables has been fit to yield data from a '28 design. The model is: y = 30+ +2.5x.2 +3,583 Where 1-3 are the cKled variables Of t, T', P, respectively. (5 pts) (l) Is point t = 90min. T = 287.50C, P 52.73psi on the path of Steepest ascent? (3 pts) (2) For a new operating point, if t = 35 min. What should be the values for T and P that the new point is on the path of the steepest ascent?
