TWO-FACTOR EXPERIMENTS WITH REPLICATION

Suppose that the experiment of Problem 16.21 was carried out in the southern part of the United States and that the columns of Table 16.32 now indicate four different types of fertilizer, while a similar experiment performed in the western part gives the results shown in Table 16.40. Determine at the 0.05 significance level whether there is a difference in yields due to (a) the fertilizers and (b) the locations. Use MINITAB to build your ANOVA.
