Question: An experiment was conducted on a chemical process that produces a polymer. The four studied were temperature (A), catalyst concentration (B), time (C), and pressure (D). Two responses, molecular weight and viscosity, were observed. The design matrix and response are shown in Exam rubric worksheet PR5.
- Consider only the molecular weight response. Plot the effect estimates on a normal probability scale. What effects appear important?
- Use ANOVA to confirm the results from part (a). Is there indication of curvature?
- Using the results from your DOE and ANOVA, write down the best fitted regression model (do not run a regression analysis) to predict molecular weights as a function of the important variables.
- Repeat parts (b-c) using viscosity as the response.
