3. Aircraft are used to sow seed and to spread fertilizer. Suppose that in a large field we set up a grid pattern in the following way: Flying east and west, a plane sows av strips, that is, a strips with each of v varieties. Flying north and south, the pilot spreads fertilizer, b strips for each of t fertilizer treatments. The intersection of a sowing strip and a fertilizer strip is a plot. There are avbt of these, and n observations are made from each of them. In both directions, the varieties or the fertilizers are assigned to the strips at random. Write the model for this experiment and develop the analysis of variance table for this design
