Based on your observations in question 1 to 3, what is the significance of a dilation when 0 < n < 1? what is the significance when n = 1? what about when n > 1? explain in terms of the size of the image and the preimage.

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
