Project 4. Car colors. We have heard that more white cars are sold in the United States than any other color. What percentage of the cars driven by students at your school are white? Answer this question by collecting data and giving a confidence interval for the proportion of white cars. You might collect data by questioning a sample of students or by looking at cars in student parking areas. In your discussion, explain how you attempted to get data that are close to an SRS of student cars.
