Traffic accidents: Traffic engineers compared rates of traffic accidents at intersections with raised medians with rates at intersections with two-way left-turn lanes. They found that out of 4656 accidents at intersections with raised medians, 2196 were lo rear-end accidents, and out of 4573 accidents at two-way left-turn lanes, 2076 were rear-end accidents. Part: 0/2 Part 1 of 2 (a) Assuming these to be random samples of accidents from the two types of intersection, construct a 99.8% confidence for the difference between the proportions of accidents that are of the rear-end type at the two types of intersection. Use the TI-84 calculator and round the answers to three decimal places. Let p, represent the population for accidents at intersections with raised medians. A 99.8% confidence interval for the difference between the proportions of accidents that are of the rear-end type at the two types of intersection is Part: 1/2 Part 2 of 2 (b) Does the confidence interval contradict the claim that the proportion of rear-end accidents is the same at both types of intersection? Because the confidence interval does not contain 10, it does not contradict the claim that the proportion of rear-end accidents is the same at both types of intersection
