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 three categories (0-1, 2, and 3) and divide by the total number of students. The sum of the frequencies for those three categories is 6+7+3=16. Dividing by 25, we get 16/25=0.64, which is closest to C. Therefore, the proportion of students absent for 3 or less days is 0.64 or 64%.
