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: 1,5,8,10,11,6,8,9,15,5,8. Week 2:7,9,11,12,8,10,11,18,9,10.
To find the range of the number of push-ups people did each week, we first need to find the minimum and maximum number of push-ups done in each week.
For Week 1:
Minimum: 1
Maximum: 15
For Week 2:
Minimum: 7
Maximum: 18
Now, we can find the range for each week:
Range for Week 1: 15 - 1 = 14
Range for Week 2: 18 - 7 = 11
Therefore, the range of the number of push-ups people did each week is 14 for Week 1 and 11 for Week 2.
