A farmer believes that his new irrigation method would result in more crop yield than the old one. To test his theory, he applies the new method to his corn fields. A total of 6 acres of sweet corn and 8 acres of flour corn are tested for the study. The farmer also thinks the method will work differently on sweet corn and flour corn. Therefore, he divides the group into sweet corn and flour corn and then randomizes the two methods within each group. The trainer measures the yield per acre, and then measures it again one year after the method has been implemented.
Select one or more:
a. The subjects are the yield of corn.
b. The treatments are the yield of corn.
c. This is an example of a block design.
d. The treatments are the new and old irrigation methods.
e. The subjects are the 6 acres of sweet corn and 8 acres of flour corn.
f. This is an example of a matched pairs experiment.
g. This is an example of a completely randomized experiment.

A farmer is planning his spring planting. He has 20 acres on which he can plant a combination of Corn, Pumpkins and Beans. He wants to maximize his profit but there is a limited demand for each crop. Each crop also requires fertilizer and irrigation water which are in short supply. There are only 50 acre ft of irrigation available and only 8,000 pounds/acre of fertilizer available. The following table summarizes the data for the problem. Crop Profit per Acre...
