In week 1, the median number of push-ups is 8.

In week 2, the median number of push-ups is 10.

The increase in the median number of push-ups from the first week to the second week is 2.

Therefore, the increase in the median number of push-ups is 2 push-ups.

Answer 2

The range of the number of push-ups people did in Week 1 is __.

The range of the number of push-ups people did in Week 2 is __.

Answer 3

[AI-generated answer — Bot GPT 3.5]

Range is the difference between the highest and lowest values in a dataset.

Week 1:
Highest number of push-ups = 15
Lowest number of push-ups = 5
Range in Week 1 = 15 - 5 = 10

Therefore, the range of the number of push-ups people did in Week 1 is 10.

Week 2:
Highest number of push-ups = 18
Lowest number of push-ups = 7
Range in Week 2 = 18 - 7 = 11

Therefore, the range of the number of push-ups people did in Week 2 is 11.
