Hey!
-------------------------------------------------
The range in a data is the value of subtracting the highest value to the lowest value.
-------------------------------------------------
First, we need to the the values in order from least to greatest.
26, 27, 27, 30, 32, 33, 33, 34, 40, 45
Second, we subtract the greatest value to least value.
45 - 26 = 19
-------------------------------------------------
Hence, the range is 19!

Hope This Helped! Good Luck!
