Many people who commute to work by car in New York City every day use either the George Washington Bridge or the Lincoln Tunnel. A random sample of commuters who use one of these two routes was obtained, and each was asked whether they carpooled to work. The data are given in the following table.

Commuting route	Sample size	Number who carpool
Bridge	1055	530
Tunnel	1663	825

a. Verify that the nonskewness criterion inequalities are satisfied.

b. Is there any evidence to suggest that the proportion of carpoolers crossing the George Washington Bridge is greater than the proportion of carpoolers using the Lincoln Tunnel? Use a = 0.01.

c. Find the p value associated with the hypothesis test in part (b).
