Hello everybody!
can you me with this problem!
you very much!

here is the problem:

karen said that it is always possible to draw either a line of best fit or a curve of best fit for a scatter plot. do you agree or disagree? explain.

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
