Weeds are common in corn fields. Does the presence ofweeds reduce the yield of the corn? Researchers planted corn in five plots of ground, then divided each plot in half. In each plot, one half was randomly selected and weeded, while the other half was not. Here are the yields of corn (bushels per acre) in each section of the test area: Plot: 1 2 3 4 5 Weeded half: 166.7 172.2 165.0 176.9 158.2 Unweeded half: 158.6 176.4 153.1 156.0 155.0 (a) Determine the value of the test statistic for the appropriate rank test.
