Quizplus · Accepted Answer

The most appropriate chi-square test for this situation is the test of independence because we want to determine if there is an association between coupon redemption and gender, which are two categorical variables. The other options are not applicable to this situation:

B) Homogeneity is used when we want to compare proportions or frequencies across multiple groups or categories.

D) Proportional is not a type of chi-square test.

E) None of the above is not a valid answer as there is a suitable chi-square test for this situation.
