Tuition, 2008. The data set provided contains the average tuition of private four-year colleges and universities as well as the average 2007–2008 tuitions for each state seen in Exercise 25.

The mean tuition charged by a public two-year college was $2763, with a standard deviation of

$988. For private four-year colleges the mean was $21,259, with a standard deviation of $6241. Which would be more unusual: a state whose average public two-year college is

$700 or a state whose average private four-year college tuition was $10,000? Explain.
