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 was the median number of hours spent outside for the kids she surveyed?
{0,10,15,4,70,15,18,20,6,8,10,12,15,18,20,2,50,40,10} (1 point)
The median number of hours spent outside by the kids that the director surveyed was
hours.
The numbers need to be arranged in ascending order: {0, 2, 4, 6, 8, 10, 10, 10, 12, 15, 15, 15, 18, 18, 20, 20, 40, 50, 70}
There are 19 numbers in the list, so the middle number (or numbers if there is an even number of data) will be the median.
In this case, the median is the 10th number in the list, which is 12.
Therefore, the median number of hours spent outside for the kids surveyed was 12 hours.
no
I apologize for the error.
Let's arrange the numbers in ascending order: {0, 2, 4, 6, 8, 10, 10, 10, 12, 15, 15, 15, 18, 18, 20, 20, 40, 50, 70}
Since there are 19 data points, the median will be the 10th value when the data is arranged in ascending order. In this case, the median is 12 hours.
Therefore, the correct median number of hours spent outside for the kids surveyed is 12 hours.
