The National Hockey League’s Florida Panthers play in the BB&T center. The cost of parking is $20. However, Lexus occasionally pays the cost by offering free parking to drivers of Lexus cars. A statistician wanted to estimate the cost of this program. He randomly sampled 300 cars entering the parking lot and recorded whether the car was a Lexus (2) or not (1).
