Question

Exercise 43 compares the responses of customers in a survey depending on how a question about their satisfaction with their car was phrased.
(a) Quantify the amount of association between the type of question and the degree of satisfaction.
(b) Combine the counts of very satisfied with somewhat satisfied, and very dissatisfied with somewhat dissatisfied, so that the table has only two rows rather than four. What happens to the degree of association if the table merges the satisfied categories into only two rows rather than four?
