In a previous matched pairs lab we tested the following hypotheses, where ? is the mean of the differences in corn yield for a plot of land (regular seed minus kiln-dried ): H0 : µ = 0 and Ha : µ < 0. In a random sample of 11 seeds of each type, the mean of the differences in the sample was -33.7. Here is a StatCrunch print-out of the hypothesis test.
