The drug Finasteride is marketed as Propecia to help protect against male pattern baldness, and it also may protect against prostate cancer. A large sampleof healthy men over age 55 were randomly assigned to receive either a daily Finasteride pill or a placebo. The study lasted seven years and the men had annual check-ups and a biopsy at the end of the study. Prostate cancer was found in 804 of 4368 men taking Finasteride and in 1145 of the 4692 men taking a placebo. 1. Assume that the true risk of developing prostate cancer for a man taking Finasteride is equal to the one in this sample. If 10 men from the Finasteride groupare randomly selected, what is the probability that at least one of them will develop prostate cancer? 2. The odds of prostate cancer among patients in the Finasteride group are _________ times those among patients in the placebo group. 3. The odds of patients in the Finasteride group having prostate cancer are __________ % less than the odds of prostate cancer among patients in the placebo group.
