In a study of hypnosis, breathing patterns were observed in an experimental group of subjects and in a control group. The measurements of total ventilation (liters of air per minute per square meter of body area) are shown. (These are the same data that were summarized in Exercise 7.5.6.) Use a Wilcoxon-Mann-Whitney test to compare the two groups at α = 0.10. Use a non-directional alternative.
