1. Here is data testing dosage amounts for a new drug used to treat pain. Due to its recent development, researchers want to know what is the appropriate dosage to treat chronic pain in arthritis patients. Each participant was given either a sugar pill, 50 mg, or 100 mg of the new medication. It is predicted that the 50 mg will be more effective than the placebo, and the 100 mg will be more effective than both the placebo and 50 mg. After a month, each participant rated their pain level. The higher the value, the more pain they felt. Use alpha = .05 Placebo/Sugar Pill 50 mg 100 mg X1 = 14 X2 = 12 X3 = 7 %3!
