The contingency table shows the results of a random sample of patients with obsessive-compulsive disorder after being treated with a drug or with a placebo. At α = 0.10, perform a homogeneity of proportions test on the claim that the proportions of the results for drug and placebo treatments are the same.

Performing a homogeneity of proportions test requires that the observed frequencies be obtained using a random sample, and each expected frequency must be greater than or equal to 5.
