Reference no: EM131813656

Question: The mean yield for hard red winter wheat in a certain state is 44.8 bu/acre. In a pilot program a modified growing scheme was introduced on 35 independent plots. The result was a sample mean yield of 45.4 bu/acre with sample standard deviation 1.6 bu/acre, an apparent increase in yield.

a. Test at the 5% level of significance whether the mean yield under the new scheme is greater than 44.8 bu/acre, using the critical value approach.

b. Compute the observed significance of the test.

c. Perform the test at the 5% level of significance using the p-value approach. You need not repeat the first three steps, already done in part (a).
