A research study was conducted to examine the clinical efficiency of a new antidepressant. Depressed patients were randomly assigned to one of three groups: a placebo group, a group that received a low dose of the drug, and a group that received a moderate dose of the drug. After four weeks of treatment, the patients completed the Beck Depression Inventory (BDI). The higher the score, the more depressed the patient. The data are presented below. Compute the appropriate test using a 0.05 significance level.

Placebo	Low Dose	Moderate Dose
38	22	14
47	19	26
39	8	11
25	23	18
