Chapter 9.5, Problem 18MS

Car count (S). You wonder how many cars there are in your area. You call up the Honda dealership and ask how many Hondas they’ve sold. They report that they’ve sold a total of 10,000 cars. You then take a lawn chair and camp out on the most traveled roadway in town and count cars. You count 800 cars and note that 250 of them are Hondas. Estimate the number of cars in your area. Do you believe you would have gotten more, less, or the same accuracy if you had called the Lexus dealership instead of the Honda? Explain.
