A car manufacturer is concerned that dealers conceal unhappy customers by keeping them out of surveys conducted by the factory. The manufacturer suspects that certain dealers enter incorrect addresses for dissatisfied customers so that they do not receive the satisfaction survey that is mailed by the manufacturer. If a current survey of the 65 customers at a dealership indicates 55% rate its service as exceptionally good, can the manufacturer estimate the proportion of all customers at this dealership who feel that its service is exceptionally good? Can it estimate the proportion at other dealerships?
