20.24 (EX) Drug testing in schools, continued 1/4: In 2002 the Supreme Court ruled that schools could require random drug tests of students participating in competitive after-school activities such as athletics. Does drug testing reduce use of illegal drugs? A study compared two similar high schools in Oregon. Wahtonka High School tested athletes at random and Warrenton High School did not. In a confidential survey, 7 of 135 athletes at Wahtonka and 27 of 141 athletes at Warrenton said they were using drugs. Regard these athletes as SRSS from the populations of athletes at similar schools with and without drug testing. Do the data give good reason to think that drug use among athletes is lower in schools that test for drugs? Take p₁ and p2 to be the proportions of athletes that use drugs, in all high-schools without drug testing and with drug testing, respectively. The hypotheses to be tested are: O Ho: P1 O Ho: P1 O Ho: P1 O Ho: P1 P2, H₂: P₁ P2 P2, H₂: P₁ P2, Ha: P1 P2, H₂: P1 P2 P2 P2
