The mean number of hours spent on screens for the kids surveyed is 13.4 hours.
To find the mean, add up all the hours and divide by the number of kids surveyed:
0+7+8+8+10+11+14+15+17+17.5+18+18+18+20+30 = 204.5
Mean = 204.5 / 15 = 13.66666667
Rounded to the nearest tenth, the mean number of hours spent on screens is 13.4 hours.
