Answer:
8
Explanation:
When finding the range, you have to subtract the smallest value from the biggest value,
2, 9, 7, 9, 1, 6
⇒ 1, 2, 6, 7, 9, 9
If we take a look at the set of numbers, we can see that 1 is the smallest value and 9 is the biggest,
Now that know that we need to subtract,
9 - 1
= 8
Therefore the range of this set of numbers is 8.
