The drug Finasteride is marketed to help protect against male pattern baldness, and it also may protect against prostate cancer. A large sample of 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. Suppose that you want to test the alternative hypothesis that the true proportion 01 healthy men over 55 who take placebo that will develop prostate cancer is greater than 20%. What is me value of the test statistic that you will use for this test? 0 Z = 0.244 0.20 0.20( I o.20) 9060 O 2 (12441120 0.244(10244) 9060 O 2 0244020 0.244(10244) I949 0 Z 0.244-0.20 0.20( l o.20) I949 0.244 0.20 O z l Screenshot l 0.20( l 0.20) 4-692
