Based on the data displayed in the histogram, the percentage of students who study 2 or more hours for the midterm is 88%.
<h3>What percentage study 2 hours or more?</h3>First, find the number of students studying:
= 3 + 9 + 6 + 3 + 2 + 1 + 1
= 25
The number of students studying 2 or more hours for the exam are:
= 9 + 6 + 3 + 2 + 1 + 1
= 22 students
The percentage studying for two hours or more is:
= 22 / 25
= 88%
