Given:
Histogram of students spent time on chores.
To find:
How many students spend 81 to 100 minutes.
Solution:
In the histogram, x-axis shows time in minutes and y-axis shows number of students (frequency).
Step 1: Look at the histogram, 5th box is 81 - 100 minutes.
Step 2: See the corresponding y- value for 81 - 100.
Step 3: The corresponding y - value lies between 2 and 4.
Step 4: Number lies between 2 and 4 is 3.
Therefore 3 students spend 81 to 100 minutes on chores.
