Question

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

10 percent level of significance.

H0​:

μ d=0

against
