archer for Based on advancements in drug therapy, ceutical company is developing Resitnan, a new reatment depression. A medical company is studying the effectiveness of Resithan as compared to their existing drug, Exemor. A random sample of 519 depressed individuals is selected and treated with Resithan, and 198 find relief from their depression. A random sample of 427 depressed individuals is independently selected from the first sample and treated with Exemor, and 128 find relief from their depression. Based on the medical researcher's study can we conclude, at the 0.01 level of significance, that the proportion p₁ of all depressed individuals taking Resithan who find relief from depression is greater than the proportion P₂ of all depressed individuals taking Exemor who find relief from depression? Perform a one-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.
