A beet farmer owns two plots of land that are equal in area but with different soil conditions. The farmer wants to compare the average annual crop yields from the two plots. The farmer selects a random sample of ni = 6 years and gathers data for these years on the first plot's yield. He also selects a random sample of n2 = 7 years and gathers data for these years on the second plot's yield. Then he computes the mean yield for each sample. Suppose that the annual crop yield from the first plot is normally distributed with Hi = 1,489 and of = 22,052, and that the annual crop yield from the
