Answer:

18 students

Explanation:

Assuming there are 21 students in the class,

3 of them slept for 12 - 15 hours

8 of them slept for 8 - 11 hours

8 of them slept for 4 - 7 hours

2 of them slept for 0 - 3 hours

Now we just add the number of students that slept under 12 hours

8 + 8 + 2 = 18 students

Hope this helps!
