Answer:
See below in bold.
Explanation:
32, 28, 22, 28, 16, 12, 20, 22, 20
Rearrange in ascending order:
12, 16, 20, 20, 22, 22, 28, 28, 32 So:
Minimum = 12.
Median = 22 ( the median is the middle number).
Maximum = 32.
Q1 = 18 (This is the Lower Quartile: 18 is the mean of 16 and 20).
Q3 = 28 (The Upper Quartile)
