Question

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 five private colleges in the United States revealed the following endowments (in millions of dollars): 188.9, 249.3, 124.7,  157.6, and  222.8. What value will be used as the point estimate for the standard deviation of endowment of all private colleges in the United States?
