Problem 15E

The article “Vehicle-Arrival Characteristics at Urban Uncontrolled Intersections” (V. Rengaraju and V. Rao, Journal of Transportation Engineering, 1995:317-323) presents data on traffic characteristics at 10 intersections in Madras, India. The following table provides data on road width in m (x1), traffic volume in vehicles per lane per hour (x2), and median speed in km/h (x3).

a. Fit the model Find the P-values for testing that the coefficients are equal to 0.

b. Fit the model . Find the P-values for testing that the coefficients are equal to 0.

c. Fit the model Find the P-values for testing that the coefficients are equal to 0.

d. Which of the models (a) through (c) do you think is best? Why?
