Two sample tests for proportions

Researchers want to test the effectiveness of a new medication to treat depression. In a randomized experiment, 7171 out of 200200 people taking the medication report symptoms of depression. Of the people receiving a placebo, 9292 out of 200200 report symptoms of depression.
To see if the medication is working any differently than the placebo, the researchers perform a test of
Ho:p1=p2H_o: p_1=p_2
Ha:p1p2H_a: p_1 \ne p_2
where p1p_1 is the true proportion of individuals like the ones in this study who take the new medication and report symptoms of depression, and p2p_2 is the true proportion of individuals like the ones in this study who take a placebo and report symptoms of depression.
