The matched pairs t test (Example 18.4) works well, and gives P = 0.3652. Letscompare the Wilcoxon signed rank test.(a) What are the ranks for the absolute values of the differences in Table 18.1?What is the value of W+?(b) What would be the mean and standard deviation of W+ if the null hypothesis(scent makes no difference) were true? Compare W+ with this mean (in standarddeviation units) to reach a tentative conclusion about significance.
