Question

This line plot shows how many hours of homework twelve students have. ​

Answer 1

2 ¹/₂ hours

Explanation:

From inspection of the given line plot:

• Most number of hours of homework = 4 ¹/₂
• Least number of hours of homework = 2

To find the difference between the most and least number of hours of homework, subtract the smaller number from the larger number:

`\sf \implies 4 (1)/(2) - 2 = 2 (1)/(2)`

Therefore, the difference, in hours, between the student with the most homework and the student with the least homework is 2 ¹/₂ hours.

Answer 2

• A. 2 1/2 hours

Explanation:

This is about the range of the data.

The student with the most homework spent 4 1/2 hours and the student with the least homework spent 2 hours.

The difference is:

• 4 1/2 - 2 = 2 1/2 hours

Correct choice is A
