PLEASE HELPthe lifespans of lions in a particular zoo are normally distributed. the average lion lives 12.5 years the standard deviation is 2.4 years use the emperical rule (68-95-99.7) to estimate the probability of a lion living between 5.3 and 10.1 years ​

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
