One Texas franchise owner conducted a study to determine whether the marketing manager’s statement was accurate for his franchise’s customers. He selected a simple random sample of 10 customers and determined the number of miles each had driven the car between oil change. He obtained the following sample data:

3,734 3,208 3,311 3,920 3,902
