Hey, good to see you again. A) 67.2 Step 1: Understand the relationship between standard deviation and variance. The variance ($\sigma^2$) is the square of the standard deviation ($\sigma$). $$\sigma^2 = (\sigma)^2$$ Step 2: Substitute the given standard deviation into the formula. Given standard deviation $\sigma = 8.2$. $$\sigma^2 = (8.2)^2$$ Step 3: Calculate the variance. $$\sigma^2 = 8.2 \times 8.2$$ $$\sigma^2 = 67.24$$ Step 4: Compare the result with the given options. The calculated variance is $67.24$. Option A is $67.2$, which is the closest value. The final answer is $\boxed{\text{A) 67.2}}$. Send me the next one 📸
