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 512 depressed individuals is selected and treated with Resithan, and 173 find relief from their depression. A random sample of 432 depressed individuals is independently selected from the first sample and treated with Exemor, and 141 find relief from their depression. Based on the medical researcher's study can we conclude, at the 0.10 level of significance, that the proportion p₁ 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.

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 512 depressed individuals is selected and
treated with Resithan, and 173 find relief from their depression. A random sample of 432 depressed individuals is independently selected from the first sample
and treated with Exemor, and 141 find relief from their depression.
Based on the medical researcher's study can we conclude, at the 0.10 level of significance, that the proportion p, 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?
