Hey, good to see you again. A) 67.2 Step 1: Understand the relationship between standard deviation and variance. The variance (^2) is the square of the standard deviation (). ^2 = ()^2 Step 2: Substitute the given standard deviation into the formula. Given standard deviation = 8.2. ^2 = (8.2)^2 Step 3: Calculate the variance. ^2 = 8.2 × 8.2 ^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 A) 67.2. Send me the next one 📸
