Question:

In an agronomic field experiment, blocks of land were subdivided into two plots of 346 square feet each. Each block provided two paired observations: one for each of the varieties of wheat. The plot yields (lb) of wheat are given in the table.5
(a) Calculate the standard error of the mean difference between the varieties.
(b) Test for a difference between the varieties using a paired t test at α = 0.05. Use a non directional alternative.
(c) Test for a difference between the varieties the wrong way, using an independent-samples test. Compare with the result of part (b).
