An experiment is performed to test the effect on corn yield of four different fertilizer treatments (A, B, C, and D) and of soil variations in two perpendicular directions. The Latin square of Table 16.42 is obtained, where the numbers show the corn yield per unit area. Test at the 0.01 significance level the hypothesis that there is no difference between (a) the fertilizers and (b) the soil variations. Use STATISTIX to build your ANOVA.
