The business college computing center wants to determine the proportion of business students who have personal computers (PC's) at home, because if the proportion exceeds 35%, then the lab will scale back a proposed enlargement of its facilities. Suppose 200 business students were randomly sampled and 85 have PC's at home. Should they use a hypothesis test or a confidence interval to answer this question? Confidence interval. Hypothesis test.
