answers below:
10
12
18
20

Answer 1

To find the range of a data set, you subtract the smallest value from the largest value.

1. Identify the smallest and largest numbers in the data set:
- Smallest: 10
- Largest: 28

2. Calculate the range:
\[
\text{Range} = \text{Largest} - \text{Smallest} = 28 - 10 = 18
\]

So, the range of the data set {10, 18, 21, 28, 12, 20} is **18**.
