Breathing Pattern Statistics

#4 In a study of hypnosis, breathing patterns were observed in an experimental group of subjects in a control group. The measurements of total ventilation (liters of air per minute per square meter of body area) are shown below. We want to know whether the groups follow the same distribution. Unfortunately, we cannot assume the distributions are normal.

Experimental group 6.06 5.60 6.76 5.32 6.32 6.34 5.74 7.18
Control group 4.50 5.41 5.70 4.86 6.21 4.79 6.08 4.78

4.1 Which test should we use?

4.2 Calculate the test statistic

4.3 Are the distributions different?
