.78 Xr14-78Refer to Exercise 14.14. Despite failingto show that differences in the three types of fer-tilizer exist, the scientist continued to believe thatthere were differences, and that the differences weremasked by the variation between the plots of land.Accordingly, he conducted another experiment. Inthe second experiment he found20 three-acre plotsof land scattered across the county. He divided eachinto three plots and applied the three types of fertil-izer on each of the one-acre plots. The crop yieldswere recorded.a. Can the scientist infer that there are differencesbetween the three types of fertilizer?b. What do these test results reveal about the vari-ation between the plots?
