Assume that you want to test the claim that the paired sample data come from a population for which the mean difference is μd=0. 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. You wish to test the following hypothesis at the 10percent level of significance. H0​: μd=0 against H1​: μd≠0. What is the value of the appropriate test​ statistic? Round to three decimal places. 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
