a- slope : 1/3; y- intercept : 3
b-slope 1/3; y-intercept : -3
c-slope : 3 ; y-intercept : -3
d- slope : 3; y-intercept : 3

Suppose that 3% of all athletes are using the endurance-enhancing hormone epo (you should be able to simply compute the percentage of all athletes that are not using epo). for our purposes, a “positive” test result is one that indicates presence of epo in an athlete’s bloodstream. the probability of a positive result, given the presence of epo is .99. the probability of a negative result, when epo is not present, is .90. what is the probability that a randomly selected athlete tests positive for epo? 0.0297
