Quizplus · Accepted Answer

To find the proportion of students absent for 3 or less days, we need to add up the frequencies for the first four classes (0-1, 2-3, 4-5, and 6-7) since they represent the days absent that are 3 or less. 
The frequency for the first class (0-1) is 5, the frequency for the second class (2-3) is 8. 
So the total frequency for students absent for 3 or less days is 5+8 = 13.
To find the proportion, we divide 13 by the total number of students (25): 
13/25 = 0.52 or 52%, which is closest to 48%.

Therefore, the best choice is C.
