Two popular drugs used for the treatment of depression are Resithan and Exemor. A random sample of 402 depressed individuals is selected and treated with Resithan, and 122 find relief from their depression. A random sample of 439 depressed individuals is independently selected from the first sample and treated with Exemor, and 158 find relief from their depression. Can we conclude, at the 0.1 level of significance, tha the proportion p, of depressed individuals taking Resithan who find relief from depression is less 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.)
