Determine the decision criterion for rejecting the null hypothesis in the given hypothesis test; i.e., describe the values of the test statistic that would result in rejection of the null hypothesis. A farmer has decided to use a new additive to grow his crops. He divided his farm into 10 plots and kept records of the corn yield (in bushels) before and after using the additive. The results are shown below.
Plot Before After
1 9 10
2 9 9
3 8 9
4 7 8
5 6 7
6 8 10
7 5 6
8 9 10
9 10 10
10 11 12
You wish to test the following hypothesis at the
10 percent level of significance.
H0:
μ d=0
against
H1:
μ d ≠0.
What decision rule would you use?

are randomly selected. The cars are driven both with and without
the additive. The results are displayed in the following table. Can
it be concluded, from the data, that the gasoline additive does
significantly increase mileage? Let d = (gas mileage with additive)
