A simple random sample of 12 small cars were subjected to a head-on collision at 40 miles per hour. Of them 8 were totaled, meaning that the cost of repairs is greater than the value of the car. Another sample of 15 large cars were subjected to the same test, and 5 of them were totaled. Find a 95% confi- dence interval for the difference in the proportions of small cars and large cars that are totaled.
