An experiment was performed to improve the yield of a chemical process. Four factors were selected, and two replicates of a completely randomized experiment were run. The results are shown in the following table:
a- Prepare an analysis of variance table and determine which factors are important in explaining yield. Factor A is significant – True or False Factor B is significant – True or False Factor C is significant – True or False Factor D is significant – True or False b- What is the P-value in the ANOVA table? Factor A: Factor B: Factor C: Factor D: c- Develop a regression model for predicting yield
d- Plot the residuals on a normal probability scale.Does the residual analysis appear satisfactory (Normal Distribution)? Is the residual Normal: Yes or No e- Provide the factorial and interaction plots.Where would you recommend that the process be run with respect to the four variables?
