Refer to Exercise 13.31. Suppose that we now find out that the 16 experimental units were obtained in the following manner. One sample was taken from each of four locations, each individual sample was split into four parts, and then each method was applied to exactly one part from each location (with the proper randomization). The data are now presented more correctly in the form shown in the accompanying table. Does this new information suggest a more appropriate method of analysis than that used in Exercise 13.31? If so, perform the new analysis and answer the question in Exercise 13.31(a). Is this new information worthwhile?
