Two popular drugs used for the treatment of depression are Resithan and Exemor. A random sample of 451 depressed individuals is selected and treated with Resithan, and 204 find relief from their depression. A random sample of 598 depressed individuals is independently selected from the first sample and treated with Exemor, and 252 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 fill in the table below.

Carry your intermediate computations to at least three decimal places and round your answers as specified in the table. (If necessary, consult a list of formulas.)

Can you help me figure out the value of the test statistic and the critical value at0.05 level of significance. A spreadsheet to input information would be extremely helpful as well. Thanks.
