Suppose from a sample of data, we have X passengers nally show up for a ight while n people booked the
tickets. (a). [5 point] State the hypothesis test (with the formula of test statistic) could be used to see if the show-up ratio of people booked tickets is larger than 0.7. (b). [10 point] Find the formula for the P-value for the hypothesis test, and state your understanding of it and make sure it is understandable by people (mostly your future colleagues, bosses or clients) without much statistic background. 3. Hint: No doubt at all, people will throw it away if your writing version of explanation is too long, say, more than half a page. If you can make it clear in about 4-5 sentences, I bet you can be a boss soon.
