2. For the paint example in #2, the effect of catalyst hardener concentration on paint adhesion was also studied. A score of 0 = poor adhesion, and 5 = excellent. A total of n = 5 trials were performed for each of four different concentrations, as summarized in the table below. Catalyst % 0.1% 0.5% 2.5 3.4 2.8 3.0 2.9 2.8 3.7 3.6 3.6 2.5 2.4 3.3 3.3 Using Minitab, compute the sums of squares, mean squares, F statistic, and P value for a one- way ANOVA. Include the Minitab output in your submission. Based on the P-value obtained, does the factor (catalyst %) have a statistically significant effect on paint adhesion at a 5% significance level? Paint Adhesion Score (0= poor, 5 = excellent) 0.3% 2.6 3.0 0.7% 3.9 3.5 3.7 3.4 4.0
