Automobile insurance is much more expensive for teenage drivers than for older drivers. To justify this cost difference, insurance companies claim that the younger drivers are much more likely to be involved in costly accidents.

The DMV reports the percentage of registered drivers in each age category as follows: 16% are younger than age 20; 28% are 20-29 years old; and 56% are age 30 or older. The number of accident reports for each age group is as follows:
