Explanation Calculation: It is given that a new test was first introduced prior to the 2000 Olympic games. In a sample of 830 world-class athletes, 159 did not compete in the World championships (a year before introduction of the new EPO test). Similarly, 133 of 825 potential athletes did not compete in 2000 Olympics. Denote p 1 and p 2 as the proportions of athletes who did not compete in Olympics before and after introduction of the new EPO test, respectively. The hypotheses for the test are given below: Null hypothesis: H 0 : p 1 − p 2 = 0 . That is, there is no significant difference between the proportions of athletes who did not compete in Olympics before and after introduction of the new EPO test. Alternative hypothesis: H a : p 1 − p 2 < 0 . That is, the proportion of athletes who did not compete in Olympics before introduction of the new EPO test is significantly less than the proportion of athletes who did not compete in Olympics after introduction of the new EPO test. In other words, the new test is significantly effective in deterring an athlete from participating in the Olympics. For α = 0.10 level of significance, Test for proportions : Software procedure: Step-by-step procedure to test two proportions using MINITAB software: Choose Stat > Basic Statistics > 2 Proportions
