Question

The director of a local Parks and Recreation department is interested in the number of hours kids spend outside each week. She surveys a group of 19 kids in her town and asks them how many hours they spent outside last week. Her results follow. What is the mean number of hours spent outside for the kids she surveyed? Round your answer to the nearest hundredth.

{0,10,15,4,70,15,18,20,6,8,10,12,15,18,20,2,50,40,10

Answer 1

Sum the hours: 0+10+15+4+70+15+18+20+6+8+10+12+15+18+20+2+50+40+10 = 343.
Mean = 343 ÷ 19 = 18.052631... ≈ 18.05 hours (to the nearest hundredth).
