A group of 7 students was asked, "How many hours did you watch television last week?" Here are their responses.

9, 4, 14, 13, 12, 17, 13

Find the mean number of hours for these students. If necessary, round your answer to the nearest tenth.

11.7

Step-by-step explanation:

To find the mean, you need to add up all the responses and then divide by the number of responses there are. So we would do 9 + 4 + 14 + 13 + 12 + 17 + 13. You get 82 when adding all of this up and because there are 7 responses we would divide. 82 : 7 = 11.7142857. Since you are rounding to the tenth, you get 11.7
