31. The article “Kolbe–Schmitt Carbonation of 2-Naphthol” (Industrial and Eng. Chemistry: Process and Design Development, 1969: 165–173) presented the accompanying data on percentage yield of BON acid as a function of reaction time (1, 2, and 3 hours), temperature (30, 70, and 100°C), and pressure

(30, 70, and 100 psi). Assuming that there is no three-factor interaction, so that SSE
SSABC provides an estimate of 2

, MINITAB gave the accompanying ANOVA table. Carry out all appropriate tests.
