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.
