Answer

Explanation:

Step1: Recall the formula

The standard - deviation $\sigma$ is related to the variance $\sigma^{2}$ by the formula $\sigma=\sqrt{\sigma^{2}}$.

Step2: Substitute the given variance

Given $\sigma^{2} = 36$, then $\sigma=\sqrt{36}$.

Step3: Calculate the value

$\sqrt{36}=6$.

Answer:

B. 6
