Two popular drugs used for the treatment of depression are Resithan and Exemor. A random sample of 570 depressed individuals is selected and treated with Resithan, and 218 find relief from their depression. A random sample of 457 depressed individuals is independently selected from the first sample and treated with Exemor, and 162 find relief from their depression. Can we conclude, at the 0.05 level of significance, that the proportion p, of all depressed individuals taking Resithan who find relief from depression is greater than the proportion p, 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. (If necessary, consult a list of formulas.)
