Recycling paper has some obvious benefits, but it may have unintended consequences. For example, perhaps people are less careful about how much paper they use if they know that their waste will be recycled. Researchers tested this idea by measuring paper use in two groups of experimental participants. Each person was placed in a room alone with scissors, paper and a trash can, and was told that he or she was testing the scissors. In the "recycling" group, there was also a recycling bin in the room. The amount of paper used by each participant was measured in grams. The data from each paper listed below: No recycling bin: 4,5,8,9,12,13,14,15, 23 With recycling bin: 10,11,16,19,40,43,129, 130 (Note: use these data for
questions 7-10) Researchers tested whether paper use differs between recycling and non-recycling groups. Since the data were not normally distributed, what kind of test is appropriate for this study? Wilcoxon rank-sum test Two-sample t-test Paired t-test None of those above
