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 4651 accidents at intersections with raised medians, 2185 were rear-end accidents, and out of 4576 accidents at two-way left-turn lanes, 2101 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 interval for the difference between the proportions of accidents that are of the rear-end type at the two types of intersection. Let p, denote the proportion of accidents of the rear- end type at intersections with raised medians. Use tables to find the critical value and round the answer to at least three decimal places 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
