An experiment is performed to determine the yields of five different varieties of wheat: A, B, C, D, and E. Four plots of land are assigned to each variety, and the yields (in bushels per acre) are as shown in Table 16.32. Assuming that the plots are of similar fertility and that the varieties are assigned to the plots at random, determine whether there is a difference between the yields at significance levels of (a) 0.05 and (b) 0.01. (c) Give the MINITAB analysis for this one-way classification or one-factor experiment.
