Question:

The outcomes on n = 10 simulations of a Cauchy random variable were −1.9415, 0.5901, −5.9848, −0.0790, −0.7757, −1.0962, 9.3820, −74.0216, −3.0678, and 3.8545. For the Cauchy distribution, the mean does not exist, but for this one, the median is believed to equal zero. Use the Wilcoxon test and these data to test H0: m = 0 against the alternative hypothesis H1: m ≠ 0. Let α ≈ 0.05.
