Two popular drugs used for the treatment of depression are Resithan and Exemor. A random sample of 588 depressed individuals is selected and treated with Resithan, and 201 find relief from their depression. A random sample of 417 depressed individuals is independently selected from the first sample and treated with Exemor, and 147 find relief from their depression. Can we conclude, at the 0.1 level of significance, that the proportion of all depressed individuals taking Resithan who find relief from depression is greater than the proportion of all depressed individuals taking Exemor who find relief from depression?
