Answer:
Step-by-step explanation:
Given : A certain stretch of West Street, I claim that most cars are going more than 5 miles per hour (mph) over the speed limit.
The speed limit is posted at 25 mph.
In a random sample of 70 cars, 46 of them were traveling faster than 30 mph (25+5).
Number of cars going more than 5 mph over the speed limit=46
Then, the sample proportion of cars going more than 5 mph over the speed limit will be :_
Hence, the sample proportion of cars going more than 5 mph over the speed limit =
