HELP ME PLEASE Phil collected data from several of his friends about the number of hours they spent sleeping
and the number of hours they spent playing video games on Saturday. He recorded the data in the scatter plot.
Based on the scatterplot, what is the best prediction of the number of hours one of Phil's
friends spends sleeping when the friend spends 1 hour playing video games?

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
