Private colleges and universities rely on money contributed by individuals and corporations for their operating

expenses. Much of this money is invested in a fund called an endowment, and the college spends only the interest

earned by the fund. A recent survey of eight private colleges revealed the following endowments (in millions of

dollars): 75.1, 53, 249.9, 497.2, 114.4,167.8 ,110.1, and 224.8.

Compute a 90% confidence interval for the true variance of Endowments made to private universities.
