You are interested in estimating the mean of a population. You plan to take a random sample from the population and use the sample’s mean as an estimate of the population mean. Assuming that the population from which you select your sample is normal, which of the statements about M are true? Check all that apply. The expected value of M is equal to the value of the population mean. You can only assume that the sampling distribution of M is normally distributed for sufficiently large sample sizes. You can assume that the sampling distribution of M is normally distributed for any sample size. The expected value of the sampling distribution of M is equal to the value of the population mean divided by the sample size.

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
