To find the mean number of hours spent on screens, we first add up all the hours spent and then divide by the total number of kids surveyed.

Total hours spent on screens = 0 + 7 + 8 + 8 + 10 + 11 + 14 + 15 + 17 + 17.5 + 18 + 18 + 18 + 20 + 30
Total hours spent on screens = 221.5

Number of kids surveyed = 15

Mean = Total hours spent on screens / Number of kids surveyed
Mean = 221.5 / 15
Mean = 14.8

The mean number of hours spent on screens for the kids surveyed is 14.8 hours.
