Question

A random sample of 48 traditional, mixed-use, pedestrian-friendly neighborhoods and 54 postwar, auto-oriented neighborhoods, all with comparable household income levels, revealed the following. The traditional neighborhoods averaged 14.6 daily vehicle miles traveled (VMT) per adult household member, with a standard deviation (uncorrected for bias) of 6.2 VMT. The auto-oriented neighborhoods averaged 18.9 VMT per adult household member and an (uncorrected) standard deviation of 7.3 VMT. Using the five-step hypothesis testing process, test the hypothesis of New Urbanists, that traditional neighborhoods reduce automobile usage and dependency at the α = .05 level.
