A group of 6 students was asked, "How many hours did you watch television last week?" Here are their responses.17, 5, 9, 17, 6, 9Find the mean number of hours for these students.If necessary, round your answer to the nearest tenth.
Solution
To find the mean (average) 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: 17 + 5 + 9 + 17 + 6 + 9 = 63
- Divide by the number of students: 63 ÷ 6 = 10.5
So, the mean number of hours these students watched television last week is 10.5 hours.
