Two popular drugs used for the treatment of depression are Resithan and Exemor. A random sample of 408 depressed individuals is selected and treated with Resithan, and 192 find relief from their depression. A random sample of 520 depressed individuals is independently selected from the first sample and treated with Exemor, and 211 find relief from their depression. Can we conclude, at the 0.05 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. (If necessary, consult a list of formulas.)

2-Proportion Test

In a 2-proportion test, two separate proportions are measured at the same time, and their similarity is evaluated. It is also known as a 2-proportion z-test, and a comparison of two different proportions is done in this method.
