The risk of failing for students with 1 hr or less study = 29/31 = 0.935

The risk of failing for students with more than 1 hr study = 2/31 = 0.065

The relative risk of failing for students with 1hr or less study, compared to those with more than 1 hr study = 0.935 / 0.065 = 14.4

So the risk of failing for students with 1hr or less study is about 14.4 times the risk of failing for students with more than 1 hr study. Who would have thought...
