A study examined driving performance while fatigued. The researchers had 40 college students drive a long distance in a simulator. While driving, each student performed a task. One group of student-drivers performed a verbal task continuously (continuous verbal condition); another group performed the task only at the end of the drive (late verbal condition); a third group did not perform the task at all (no verbal condition); and the fourth group listened to a program on the car radio (radio show condition). The dependent variable of interest was the percentage of billboards recalled by the student-driver. Use the accompanying data to complete parts a through b.
