The city of Berrysville, CA has been under considerable pressure to economize. Last year, the city council passed an ordinance authorizing an experimental program for the maintenance of city-owned vehicles. The bill stipulates that for 1 year, a random sample of 150 of the city’s 400 automobiles will receive no preventive maintenance and will simply be driven until they break down. The other 250 automobiles will receive regularly scheduled preventive maintenance. The council is interested in whether the expensive program of preventive maintenance reduces the number of breakdown. After a year under the experiment maintenance program, the city council was presented with the following data. Conduct a cross-tabulation to make a recommendation regarding whether the program should be continued or terminated.

Automobile Breakdown	Automobile Maintenance
	None	Regularly Scheduled	Total
No breakdown	72	194	266
Breakdown	78	56	134
Total	150	250	400
