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 a certain country revealed the endowments (in millions of dollars) of 60.2, 47.0, 235.1, 490.0, 122.6, 177.5, 95.4, and 220.0. Summary statistics yield X = 180.975 and S = 143.042. Calculate a 95% confidence interval for the mean endowment of all the private colleges sampled, assuming a normal distribution for the endowments. O A. $180.975 + 599.123 O B. $180.975 +$94.066 O C. $180.975 + $119.586 O D. $180.975 + $116.621 Click to select your
