Question
4) An agricultural experiment station was interested in comparing the yields for two new varieties of corn. Because the investigators thought there might be a great deal of variability in yield from one farm to another, each was randomly assigned to a different 1-scre plot on each of the seven farms. The difference between Variety A and Variety B is listed below.
