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 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
To find the range, we subtract the lowest value from the highest value in the dataset.
For week 1:
Range = highest value - lowest value
Range = 15 - 5
Range = 10
Therefore, the range of the number of push-ups people did in week 1 is 10.
For week 2:
Range = highest value - lowest value
Range = 18 - 7
Range = 11
Therefore, the range of the number of push-ups people did in week 2 is 11.
First, let's arrange the data in ascending order:
Week 1: 5, 5, 6, 8, 8, 8, 9, 10, 11, 15
Week 2: 7, 8, 9, 9, 10, 10, 11, 11, 12, 18
The median for week 1 is the 6th number (8) and the median for week 2 is the 6th number (10).
The increase in median number of push-ups from the first week to the second week is 2 push-ups (10 - 8 = 2).
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 did in 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
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 ___.

The dot plots represent the ages, in years, of people watching two movies at a local theater. Find the model age of the people who watched each movie.
The modal age of people who watched movie 1 is ____.
The modal age of people who watched movie 2 is ____.
incorrect
I apologize for the error. Let's reevaluate the data to find the correct modal ages for each movie.
For Movie 1:
The age that appears most frequently in the dot plot for Movie 1 is 8 times, and it corresponds to the age of 23.
Therefore, the modal age of people who watched Movie 1 is 23.
For Movie 2:
The age that appears most frequently in the dot plot for Movie 2 is 6 times, and it corresponds to the age of 38.
Therefore, the modal age of people who watched Movie 2 is 38.
To find the modal age for each movie, we look for the age that appears most frequently.
For Movie 1:
The age 28 appears 3 times, which is more than any other age. Therefore, the modal age for people who watched Movie 1 is 28.
For Movie 2:
The age 38 appears 4 times, which is more than any other age. Therefore, the modal age for people who watched Movie 2 is 38.
