To find the median number of hours spent on screens, we first need to arrange the numbers in ascending order:
0, 7, 8, 8, 10, 11, 14, 15, 17, 17.5, 18, 18, 18, 20, 30
Since we have 15 numbers, the median will be the average of the 8th and 9th numbers in this ordered list.
Median = (15 + 17)/2 = 16
Therefore, the median number of hours spent on screens by the kids surveyed is 16 hours.
The director of a local summer camp is interested in the number of hours kids spend on screens each week. He surveys a group of 15 kids at his camp and asks them how many hours they spent on screens last week. A list of his results follows. What is the median number of hours spent on screens for the kids he surveyed? Round your answer to the nearest tenth. {7,8,0,15,14,11,17.5,17,18,20,18,30,18,8,10}(1 point) The median number of hours spent on screens by the kids that the director surveyed is hours.
