To find the mean, we first need to calculate the total hours spent on math homework and then divide by the number of students.
Total hours spent: (8 * 1) + (6 * 2) + (4 * 3) + (2 * 4) + (1 * 5) = 8 + 12 + 12 + 8 + 5 = 45
Number of students: 8 + 6 + 4 + 2 + 1 = 21
Mean number of hours spent: 45 hours / 21 students = 2.14 hours
Therefore, the correct answer is D. 2.14 hours.
Number of students. 8. 6. 4. 2. 1
Number of hours. 1. 2. 3. 4. 5
