Haimere hypothesis it for the difference of population proportions Espanol 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 329 depressed Individuals Is selected and treated with Resithan, and 19/ find relief from their depression. A random sample of 508 depressed Individuals Is Independently selected from the first sample and treated with Exemor, and 148 find relief from their depression. Based on the medical researcher's study can we conclude, at the 0.Ul level of significance, that the proportion P, of all depressed Individuals taking Resithan who find relief from depression Is greater than the proportion Py of all depressed Individuals taking Exemor who find relief from depression?
