Describe two methods of deciding whether two events are independent. b. How can you tell if two categorical variables are independent in a population? Give at least two ways. c. If you have only the marginal totals, how can you determine frequencies for each cell that make the variables independent? d. If two categorical variables are independent, does knowing which category a person belongs to on the first variable help you predict which category he or she belongs to on the second variable?
