In the problem, the given data is the mean and the variance. Now to solve this problem, we must remember that the formula for variance is:

Variance = s^2

Where s is equivalent to the standard deviation, therefore:

s = sqrt (Variance)

Calculating for the value of the standard deviation given Variance = 184:

s = sqrt  (184)

s = 13.56 %                          (ANSWER)
