Ten randomly selected people were asked to join a fitness group. Over the next two weeks, they were tested on how many push-ups they could do. The data shows the number of push-ups they did over the two weeks. What is the range of the number of push-ups people did each week?
Week 1: 5, 8, 10, 11, 6, 8, 9, 15, 5, 8
Week 2: 7, 9, 11, 12, 8, 10, 11, 18, 9, 10
(1 point)
The range is the difference between the highest and lowest values in a dataset.
For week 1:
Highest: 15
Lowest: 5
Range: 15 - 5 = 10
For week 2:
Highest: 18
Lowest: 7
Range: 18 - 7 = 11
Therefore, the range of the number of push-ups people did each week is 10 for week 1 and 11 for week 2.
