Answer 1

To find the range of the number of push-ups for each week, we subtract the minimum value from the maximum value in the dataset for that week.

Week 1:

• Data: 5, 8, 10, 11, 6, 8, 9, 15, 5, 8
• Maximum: 15
• Minimum: 5

Range for Week 1 = Maximum - Minimum = 15 - 5 = 10

Week 2:

• Data: 7, 9, 11, 12, 8, 10, 11, 18, 9, 10
• Maximum: 18
• Minimum: 7

Range for Week 2 = Maximum - Minimum = 18 - 7 = 11

So the answers are:

• The range of the number of push-ups people did in Week 1 is 10.
• The range of the number of push-ups people did in Week 2 is 11.
