The transportation system of buses and commuter trains in a large metropolitan area in Canada operates on the honor system. Train travelers are expected to buy their tickets before boarding the train, but only a small number of people will be checked on the train to see whether they bought a ticket. In an investigation of lost revenue from "cheaters" on a particular route, a random sample of 500 train travelers was taken, the results of which are recorded in the "Ticket".
A. Estimate with 95% confidence the proportion of all train travelers who do not buy a ticket.
B. Assuming that there are 1 million travelers per year and the fare is 3.00 estimate with 95% confidence the amount of revenue lost each year.
