An engineer performed an experiment to increase the filtration rate (output) of a process to produce a chemical. Four factors were considered: temperature (A), pressure (B), formaldehyde concentration (C), and stirring rate (D) A B ? D Y: Filtration Rate -1 -1 -1 -1 45 1 -1 -1 1 100 -1 1 -1 1 45 1 1 -1 -1 -1 -1 1 1 75 1 -1 1 -1 60 -1 1 1 -1 80 1 1 1 1 96 1) Apply this design using Minitab software 2) What is the name of this design? Explain how we construct this design? What is the resolution of this design? Determine the aliases if each factor and of each 2-factor interaction 3) Using normality plot of the effect and Pareto chart of the effect (Minitab) verify that all factors are not significant (pay attention we can't conclude that all factors are not significant, because fractional design) 4) Using Minitab, trace the main effect plot and the 2-factor interaction plot, and determine the value of each effect and interaction, 5) Verify that B and its interactions appear to be insignificant and they can be dropped from the model, and apply the normality plot of the effect and Pareto chart of the effect (Minitab) 6) Apply ANOVA for each selected term. Conclude et validate (see the residuals behaviour) the model 7) Use Minitab for determining the optimal configuration which is gives a filtrate rate 90+10 65
