Based on advancements in drug therapy. a pharmaceutical company is developing Resithan, a new treatment for depression. A medical researcher for the company is studying the effectiveness of Resithan as compared to their existing drug, Exemor. A random sample of 445 depressed individuals is selected and treated with Resithan, and 188 find relief from their depression. A random sample of 565 depressed individuals is independently selected from the first sample and treated with Exemor, and 216 find relief from their depression. Based on the medical researcher's study can we conclude. at the 0.05 level of signicance, that the proportion pl of all depressed individuals taking Resithan who find relief from depression is greater than the proportion p2 of all depressed individuals taking Exemor who nd relief from depression? Perform a onetailed 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.
