He randomly selects 12 times between 6 am and 10 pm, and he and his assistant count the number of cars passing through each intersection during the 10-minute interval that begins at that time. He plans to test the hypothesis that the mean difference in the number of cars passing through the two intersections during each of those 12 times intervals is 0.
Which of the following is the appropriate test of the city planner’s hypothesis?
a) Two-proportion z-test
b) Two-sample z-test
