The range rule of thumb for estimating the standard deviation is to divide the range of the data set by 4. The range is the difference between the maximum and minimum values in the data set. Here, the maximum value is 36 and the minimum value is 21, so the range is $36 - 21 = 15$. Dividing the range by 4 gives $15 / 4 = 3.75$.
