11. The example at the end of Section 5.3.3 examined some data from an experiment on the effects of drinking alcohol. Another portion of the study consisted of measuring the effects of alcohol over 3 days of drinking. The scores for the control group, for the first 2 days of drinking, are 4, 47, 35, 4, 4, 0, 58, 0, 12, 4, 26, 19, 6, 10, 1, 22, 54, 15, 4, and 22. The experimental group had scores 2, 0, 7, 0, 4, 2, 9, 0, 2, 22, 0, 3, 0, 0, 47, 26, 2, 0, 7, and 2. Verify that the hypothesis of equal 20% trimmed means is rejected with α = .05. Next, verify that this hypothesis is not rejected when using the equal-tailed bootstrap-t method but that it is rejected when using the symmetric percentile t procedure instead. Comment on these results.
