Traffic Engineers Compared Rates of Traffic Collisions at Intersections with Raised

True/False

Traffic engineers compared rates of traffic collisions at intersections with raised medians and rates at intersections with two-way left-turn lanes. They found that out of 4,512 collisions at intersections With raised medians, 2,202 were rear-end collisions, and out of 4,277 collisions at two-way left-turn Lanes, 1,903 were rear-end collisions.
Assuming these to be random samples of collisions from the two types of intersections, construct a 95% Confidence interval for the difference between the proportions of collisions that are of the rear-end Type at the two types of intersection. Does the confidence interval contradict the claim that the Proportion of rear-end collisions is the same at both types of intersection?
