To calculate the mean, we sum up all the hours spent outside and divide by the total number of kids surveyed.
0 + 10 + 15 + 4 + 70 + 15 + 18 + 20 + 6 + 8 + 10 + 12 + 15 + 18 + 20 + 2 + 50 + 40 + 10 = 305
Now, divide the sum by the total number of kids surveyed (19):
305 / 19 = 16.05
Therefore, the mean number of hours spent outside by the kids surveyed is 16.05 hours.
