Assume that the significance level is a=0.05. Use the given statement and find the​ P-value and critical​ value(s). The test statistic of z=-1.44 is obtained when testing the claim that p= 1/5. Find p-value

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
