A flat rate shipping box is in the shape of a rectangular prism. You estimate that the volume of the box is 1050 cubic inches. You measure the box and find that it has a length of 14 inches, a width of 10 inches, and a height of 6.5 inches. Find the percent error. Round your answer to the nearest tenth of a percent.

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
