1. Dr. Baxter wants to demonstrate her new treatment for anxiety is more effective than the traditional treatments. She selects 30 individuals suffering from anxiety and randomly assigns them to one of three groups. She compares the (state anxiety) scores of her experimental treatment, with a conventional treatment, and a group of untreated individuals. The data are below.

1. Is treatment effective? Is Dr. Baxter's treatment more effective? (=.05)
2. Conduct post-hoc tests, where appropriate.
