Researchers conducting a clinical trial randomly assigned 60 patients with painful knee osteoarthritis evenly into one of four treatment groups: glucosamine, chondroitin, Celebrex, or placebo. After the study period, patients were asked if they experienced substantial improvement in pain and ability to function normally. Thirty-four patients replied that they did have an improvement, including 8 in the glucosamine group, 9 in the chondroitin group, 11 in the Celebrex group, and 6 in the placebo group.

Create a graph for this data that can be used to compare the success of each of the four treatments.

Conduct the appropriate test to determine if these four treatments were equally successful in improving knee pain and functionality.

Calculate the odds ratio of experiencing an improvement for patients in the Celebrex group compared those in the placebo group. Interpret what this means in the context of the problem.
