Z test & z test & estimator of p -p estimator of p 1-p 2 12. 22 estimator of s 2 /s 2 estimator of s. We would expect if it were effective that: The number of accidents would decrease, and the cost of accident repairs would be less. Data were collected on 500 cars with abs and 500 cars without. The number of cars involved in accidents was recorded, as was the cost of repairs. Is there sufficient evidence to infer that the accident rate is lower in.
