Two popular drugs used for the treatment of depression are Resithan and Exemor. A random sample of 597 depressed individuals is selected and treated with Resithan, and 251 find relief from their depression. A random sample of 556 depressed individuals is independently selected from the first sample and treated with Exemor, and 273 find relief from their depression. Can we conclude, at the 0.1 level of significance, that the proportion p, of all depressed individuals taking Resithan who find relief from depression differs from the proportion p, of all depressed individuals taking Exemor who find relief from depression? Perform a two-tailed test. Then complete the parts below. Carry your intermediate computations to three or more decimal places and round your answers as specified in the parts below. (If necessary, consult a list of formulas.) (a) State the null hypothesis H, and the alternative hypothesis H,. H, :0 H, :0 (b) Determine the type of test statistic to use. (Choose one) ▼ O=0 OSO (c) Find the value of the test statistic. (Round to three or more decimal places.) O
