Two popular drugs used for the treatment of depression are Resithan and Exemor. A random sample of 590 depressed individuals is selected and treated with Resithan, and 203 find relief from their depression. A random sample of 481 depressed individuals is independently selected from the first sample and treated with Exemor, and 179 find relief from their depression. Can we conclude, at the 0.05 level of significance, that the proportion p1 of depressed individuals taking Resithan who find relief from depression is less than the proportion p2 of all depressed individuals taking Exemor who find relief from depression? Perform a one-tailed test. The null hypothesis: H0: The alternative hypothesis: H1: The type of test statistic: (Choose one)ZtChi squareF The value of the test statistic:(Round to at least three decimal places.) The critical value at the 0.05 level of significance:(Round to at least three decimal places.) Can we conclude that the proportion of depressed individuals taking Resithan who find relief is less than the proportion taking Exemor who find relief? Yes No

Question
Two popular drugs used for the treatment of depression are Resithan and Exemor. A random sample of
590
depressed individuals is selected and treated with Resithan, and
203
find relief from their depression. A random sample of
481
depressed individuals is independently selected from the first sample and treated with Exemor, and
179
find relief from their depression. Can we conclude, at the
0.05
level of significance, that the proportion
p1
of depressed individuals taking Resithan who find relief from depression is less than the proportion
p2
of all depressed individuals taking Exemor who find relief from depression?
Perform a one-tailed test.
