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

First, identify the smallest and largest numbers in the data set:

  • The smallest number is 11.
  • The largest number is 30.

Then, the range is calculated as follows:

Range = Largest value - Smallest value = 30 - 11 = 19.

So, the correct response is:

Subtract 30−11.
