Can a secondary task-such as a word association task-improve your performance when driving while fatigued? This was the question of interest in a study. The researchers used a driving simulator to obtain their data. Each of 40 college students was assigned to drive a long distance in the simulator. However, the student-drivers were divided into four groups of 10 drivers each. Group 1 performed the verbal task continuously (continuous verbal condition); Group 2 performed the task only at the end of the drive (late verbal condition); Group 3 did not perform the task at all (no verbal condition); and Group 4 listened to a program on the car radio (radio show condition). At the end of the simulated drive, drivers were asked to recall billboards that they saw along the way. The percentage of billboards recalled by each student-driver is provided in the accompanying table. Use the appropraite analysis to determine if the mean recall percentage differs for student-drivers in the four groups. Test using a = 0.01. Click here to view the data table. What are the hypotheses? OA. Ho: H₁ H₂ H3 H4 H₂: At least two treatment means are equal O B. Ho: At least two treatment means are equal Ha: H1 H₂ H3 H4 OC. Ho: At least two treatment means differ Ha: H1 H2 H3 H4 O D. Ho: H₁ H2 H3 H4 Ha: At least two treatment means differ Identify the testystatistic. F= (Round to three decimal places as needed.) Identify the p-value. p-value = (Round to three decimal places as needed.)
