EXAM P QUESTIONS OF THE WEEK S. Broverman, 2006 Week of January 16/06 An econometric study of the population of the island of Falkvinas has found income disparities between those who have a university degree and those who do not. A Falkvinian who is chosen at random from all Falkvinians with a university degree has an annual income that is normally distributed with a mean of 80,000 BA (the Falkvinian currency is the BritArg) and a standard deviation of 20,000 BA. A Falkvinian who is chosen at random from all Falkvinians without a university degree has an annual income that is normally distributed with a mean of 100,000 BA (the Falkvinian currency is the BritArg) and a standard deviation of 40,000 BA. Suppose that Cedric is a randomly chosen Falkvinian with a university degree and Juan is a randomly chosen Falkvinian without a university degree. Find the probability that Juan's annual income is at least 30,000 BA greater than Cedric's annual income.
