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 =
You need to plug K in and solve for K.
6=K4
6/4=K
you can reduce to 3/2=K
