Those who use the method claim that it can reduce swelling. Researchers compared three? treatments: (1) contrast baths and? exercise, (2) contrast baths? alone, and? (3) exercise alone. They report the boxplots to the? right, comparing the change in hand volume after treatment. Answer parts a through c below.1) The researchers conclude that the differences were not statistically significant. Explain what that means in cona) There is no evidence that the changes in swelling were different among the three treatments. Contrast? baths, with or without? exercise, did not appear to reduce swelling any more than exercise alone.b) There is evidence that the three treatments have no effect since the differences between the isolated treatments and the combined treatment are not statistically different. All three treatments appear to be useless for reducing swelling.c) There is evidence that the changes in swelling were different among the three? treatments, but not enough data to tell which treatment was most effective. All three treatments appear to cause an unknown but unequal reduction in swelling.d) There is no evidence that the changes in swelling were different among the three treatments. The experiment should be run again with more subjects.MathStatistics and Probability STATS 115
