An instructor asked her students how much time (to the nearest hour) they spent studying for the midterm. The data are displayed in the following histogram: What percentage of students study 2 or more hours for the midterm? % Round your answer to the nearest whole number

Answer 1

Based on the data displayed in the histogram, the percentage of students who study 2 or more hours for the midterm is 88%.

What percentage study 2 hours or more?

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%
