The percentage of hardwood concentration in raw pulp, the vat pressure, and the cooking time of the pulp are being investigated for their effects on the strength of paper. Three levels of hardwood concentration, three levels of pressure, and two cooking times are selected. A factorial experiment with two replicates is conducted, and the following data are obtained:
a) Determine the SS of cooking time. Answer in 3 decimal places. b) Determine the variance of the model. Answer in 4 decimal places. c) How many factors are significant? d) What is the maximum value of the standardized residual? answer in 2 decimal places. e) Based on your answer in (d), are the data normally distributed? Answer Yes or No. f) Using Fisher's LSD Test, which \% Hardwood concentration is the best? g) Is the level 4% Hardwood concentration better than level 8 ? Answer Yes or No.
