A marketing survey of car owners was presented in two ways.11 One wording asked the customer whether he was satisfied with his car. The other asked the customer whether he was dissatisfied. The data table has two variables, one indicating the wording of the question and one giving the level of reported satisfaction.
(a) Find the contingency table defined by the level of satisfaction and the wording of the question. Include the marginal distributions.
(b) Which group reported being more satisfied (either very satisfied or somewhat satisfied) with their cars?
(c) If a company wants to produce an ad citing this type of survey of its customers, how should it word the question?
