The yield of a chemical process is being studied. The two most important variables are thought to be the pressure and the temperature. Three levels of each factor are selected, and a factorial experiment with two replicates is performed. The yield data are is attached as picture:
Q1. What are the factors in this experiment? How many levels are considered for each factor? How many replications are on each treatment? What is the response variable? Is there a block in this experiment? What are the hypotheses of interest in this experiment? Use the following results from MINITAB to answer the following questions (Use alpha= 0.05): Test the hypothesis using P-values (Draw conclusions). Find the critical F for each hypothesis and draw conclusion. Calculate the R- Sq value. What does R-Sq value mean?
