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. From the first to the second week, what was the increase in the median number of push-ups? 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) push-ups
The median number of push-ups in week 1 is 8, and the median number of push-ups in week 2 is 10.
Therefore, the increase in the median number of push-ups from week 1 to week 2 is 10 - 8 = 2 push-ups.
