| Placebo | 20 | 100 |
Is there a significant difference in the proportions of
patients reporting pain relief?
Run the test at a 5% level of significance.
H0: p1= p2(equivalent to RD = 0, RR=1 or OR=1)
Can they reject the H0?

Yes, Reject H0, there is a statistically significant differencein the proportions of patients reporting pain relief in the newmedication and placebo groups
No, Fail to Reject H0, there is no statistically significantdifference in the proportions of patients reporting pain reliefbetween the new medication and placebo groups
