Question

The numbers of hours that 12 students say they typically spend on homework in a week are 0,2,8,8,8,8,8,8,10,10,10,10. What is the mean?

Answer 1

7.5 hours

Explanation:

The mean is found by adding up the total of the numbers, then dividing the sum over the number of numbers.

Here, it is: (0 + 2 + 8 + 8 + 8 + 8 + 8 + 8 + 10 + 10 + 10 + 10)/12.

That is equal to 90/12, which is equal to 7.5 hours.
