    Have you reviewed the definitions of the null hypothesis and alternative hypothesis, definitions that are certain to be in your class notes and textbook?

    If we are testing the hypothesis that the average difference is greater than 200 kg/acre then

    H_0:\mu_A-\mu_B\leq 200

    and

    H_A:\mu_A-\mu_B> 200

    One sided test when

    H_0:\mu_A-\mu_B\leq 200 or H_0:\mu_A-\mu_B\geq 200

    Two sided test when

    H_0:\mu_A-\mu_B= 200
