A package delivery company experiences high variability in daily customer demand, which in turns results in high variability in the daily workload at the central sorting facility. The company relies on its sorting facility employees working overtime to provide on-time delivery when the workload demand is very high. A sorting facility employee receives a salary of $12/hour for a 40 hour week, and the employee receives $17/hour for every hour worked overtime, that is for every hour worked over 40 hours in a given week. The number of overtime hours than an employee works in any given week is a random variable, with a mean of 15 hours and a standard deviation of 4 hours. What are the mean, the standard deviation, and the variance of an employee's total weekly salary?

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
