Suppose a food processing company wants to package sliced pineapples in cans. They have four different processing plants, say, A, B, C, and D. Suppose they have 56 truckloads (num- bered 1 to 56) of pineapples collected from different parts of the country. In order to get some uniformity in taste, it is better to randomly assign the trucks to the four plants. Develop a design using the random assignment procedure.
