In the study discussed in Exercise 10, the sales managers were also asked what traits they considered most important in a sales manager. The results are given in Table 12.21.

(a) Are the two independent? Explain.

(b) Calculate Pearson’s contingency coefficient. Is there a strong relationship between the traits the sales managers think are important for salespersons and those for sales managers?

Exercise 10

In Exercise 12 of Chapter 1, the traits of salespersons considered most important by sales managers were listed in Table 1.24. These data are condensed in Table 12.19. Test the hypothesis that there is no difference in the proportions of sales managers that rated the three categories as most important.
