Patrick built a robot that is 0.8 meters tall. Adelaide built a robot that is 2 feet 9 inches tall. Who has the taller robot? Explain your reasoning. (1 m = 3.3 ft)

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
