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 414 depressed individuals is selected and treated with Resithan, and 191 find relief from their depression. A random
sample of 557 depressed individuals is independently selected from the first sample and treated with Exemor, and 213 find relief
from their depression.
Based on the medical researcher's study 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 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.)
