Question

Let ?? be the average yield in bushels per acre of variety i of corn, i = 1, 2, 3, 4. In order to test the hypothesis ?0: ?1 = ?2 = ?3 = ?4 at the 5% significance level, four test plots for each of the four varieties of corn are planted. Determine whether we accept or reject ?0 if the yield in bushels per acre of the four varieties of corn are, respectively, as follows: ?1: 158,167,164
?2: 177,166.168
?3: 180,169,171
?4: 152,163,165
