For questions 27-37, use the following information. A researcher wants to test the effectiveness of three new drugs that have been developed for reducing allergy symptoms. The researcher recruits 15 participants and randomly assigns them to either take Drug A, Drug B, or Drug C for a week. At the end of the week, the researcher measures the participants' allergy symptoms on a scale from 1 to 10 (where a higher score means more allergy symptoms). The participants' scores are shown below: Drug A Drug B Drug C 2 6 9 4 5 7 3 5 6 3 7 6 3 2 7 MorugA = 3.00 MDrugB = 5.00 MDrugc = 7.00 Using the appropriate hypothesis test and the six steps of hypothesis testing, see what the researcher should conclude about the how the drugs compare in their ability to reduce allergy symptoms.
