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 provides an estimate of s2

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