Extracted text: Factorial design 2K (use MINITAB) A dairy company has had problems with the viscosity of a certain chocolate drink. It is believed that with three ingredients that are added in small quantities this problem can be solved, so it is necessary to explore the situation; for this run an experiment 2 to 3 with two replicas. The results obtained are as follows: INGREDIENT A INGREDIENT B INGREDIENT C VISCOSITY -1 -1 -1 13.3 13.9 +1 -1 -1 14.7 14.4 -1 +1 -1 14.6 14.9 +1 +1 -1 14.3 14.1 -1 -1 +1 16.9 17.2 +1 -1 +1 15.5 15.1 -1 +1 +1 17.4 17.1 +1 +1 +1 18.9 19.2 a) Estimate all possible effects and state which are significant. b) Perform variance analysis of these data and draw general conclusions. c) Interpret significant effects in detail. d) Is there a winning treatment to minimize?
