It is time for Roger Hall, manager of new car sales at the Maxwell Ford dealership, to submit his order for new Mustang coupes. These cars will be parked in the lot, available for immediate sale to buyers who are not special-ordering a car. Roger must decide how many Mustangs of each color he should order. The new color options are very similar to the past year's options.

Roger believes the colors chosen by customers who special-order their cars best reflect most customers' true color preferences. He has taken a random sample of 40 special orders for Mustang coupes placed in the past year. The color preferences found in the sample are listed below.

Blue Black Green White Black Red Red White
Black Red White Blue Blue Green Red Black
Red White Blue White Red Red Black Black
Green Black Red Black Blue Black White Green
Blue Red Black White Black Red Black Blue
