A chemical engineer has carried out an experiment to study the effects of the fixed factors of vat pressure (A), cooking time of pulp (B), and hardwood concentration (C) on he strength of paper. The experiment involved two pressures, four cooking times, three concentrations, and two observations at each combination of these levels. Calculated sums of squares are SSA = 6.94, SSB = 5.61, SSC = 12.33, SSAB = 4.05, SSAC = 7.32, SSBC = 15.80, SSE 5 14.40, and SST = 70.82. Construct the ANOVA table, and carry out appropriate tests at significance level .05?
