Answer 1

1. The mean is 28.57
You can find it by adding all the numbers on the right column then dividing by the total amount, 7
2. The median is 27 as it is the middle number listed numerically
To find the median you lost all the numbers from least to greatest then find the middle one
3. The lower quartile are the numbers behind the median so 5,7,10
4. The upper quartile are the number in front of the median so 36,48,67
5. The range is 62 you can find it by subtracting the largest number in the data set, 67, from the smallest ,5,
