Solution
To find the mean number of hours these students watched television, you need to add up all the hours and then divide by the number of students.
Here are the steps:
- Add up the hours: 7 + 12 + 13 + 17 + 16 + 8 = 73 hours
- Divide the total hours by the number of students: 73 hours ÷ 6 students = 12.16 hours
So, the mean number of hours these students watched television last week is approximately 12.2 hours (rounded to the nearest tenth).
