Question
1. In an effort to determine whether a new type of fertilizer is more effective than the type
currently in use, researchers took twelve 2-acre plots of land scattered throughout the county.
Each plot was divided into two equal-sized subplots, one of which was treated with the current
fertilizer and the other of which was treated with the new fertilizer. Wheat was planted, and the
crop yields measured. These data are in the table below
