To find the range of the data set {45, 93, 60, 72, 15, 45, 81}, we first need to identify the smallest and largest values in the set.
The smallest value is 15 and the largest value is 93.
Now, we can calculate the range by subtracting the smallest value from the largest value:
Range = Largest Value - Smallest Value
= 93 - 15
= 78
So, the range of the data set {45, 93, 60, 72, 15, 45, 81} is 78.
