Fuel Consumption and Cars
A sample of automobiles entering a parking garage in Monterey before 6:00 a.m. on a Monday morning was obtained, and each was classified as either foreign (F) or domestic (D). The ordered observations are given in the following table.
Is there any evidence to suggest that the order of automobiles entering the parking garage is not random? Use the runs test with the normal approximation and a 0.05 level of significance.
