To find the relative frequency of a score, you need to divide the frequency of that score by the total frequency. In this case, we don't know the total frequency, but we can assume it is some number (let's call it "n"). Since the frequency of 14 is 13, we can set up the following equation:

13/n = relative frequency of 14

Solving for the relative frequency, we get:

relative frequency of 14 = 13/n

We don't know what "n" is, but we do know that there are 82 total scores (since the sum of the frequencies in the table is 82). So we can substitute 82 for "n" and solve:

relative frequency of 14 = 13/82 ≈ 0.158

The closest answer choice to 0.158 is B, 0.13.
