Answer 1

To find the mean number of hours spent outside for the kids surveyed, we need to add up all the hours reported and then 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 = 285

Now, we divide by the total number of kids surveyed which is 19.

285 / 19 = 15

So, the mean number of hours spent outside for the kids surveyed is 15 hours.
