In Exercise 1, you found that more blacks than whites are likely to fear walking alone in their neighborhoods. You now wonder if this difference exists because whites are more likely to own their own homes and so live in safer neighborhoods. In other words, you want to try some elaboration.
a. Use the data from Exercise 1 to construct tables showing the relationship between fear of walking alone and race, controlling for whether the individual rents or owns his or her dwelling.
b. Does renting versus owning one's dwelling "explain" the difference in fear between whites and blacks? (Use percentage differences to support your answer.)
c. Has introducing home ownership shown that the relationship between race and fear is spurious or is home ownership an intervening variable? Explain.
