The director of a local summer camp is interested in the number of hours kids spend on screens each week. He surveys a group of 15 kids at his camp and asks them how many hours they spent on screens last week. A list of his results follows. What is the mean number of hours spent on screens for the kids he surveyed? Round your answer to the nearest tenth.

The mean number of hours spent on screens by the kids that the director surveyed is hours.

Answer 1

The sum of all the hours listed is 0 + 7 + 8 + 8 + 10 + 11 + 14 + 15 + 17 + 17.5 + 18 + 18 + 18 + 20 + 30 = 201.5

To find the mean, we divide this sum by the number of kids surveyed, which is 15.

Mean = 201.5 / 15 = 13.4

Therefore, the mean number of hours spent on screens for the kids the director surveyed is 13.4 hours.
