Private colleges and universities rely on money contributed by individuals and corporations for their operating expenses. Much of this money is put into a fund called an endowment, and the college spends only the interest earned by the fund. A recent survey of 8 private colleges in the United States revealed the following endowments (in millions of dollars): 60.2, 47.0, 235.1, 490.0, 122.6,
177.5, 95.4, and 220.0. Summary statistics yield X X = 180.975 and S = 143.042. Calculate a 95% confidence interval for the mean endowment of all the private colleges in the United States assuming a normal distribution for the endowments.
A) $180.975 ± $99.123 B) $180.975 ± $116.621
C) $180.975 ± $119.586 D) $180.975 ± $94.066
