Suppose you are interested in determining the probability that a college student will own a personal computer. You poll 8 of your classmates from randomly selected classes and find that 5 of them own their own computers. Find a 90% confidence interval estimate for the probability than any randomly selected college student will own his or her own computer. Round E and the interval limits to the nearest thousandth.
