Help me find which A,B,C, or D is the correct answer to the last part please. The brain volumes (cm3) of 50 brains vary from a low of 904 cm3 to a high of 1490 cm3. Use the range rule of thumb to estimate the standard deviation s and compare the result to the exact standard deviation of 191.4 cm3, assuming the estimate is accurate if it is within 15 cm3. The estimated standard deviation is 146.5 cm3. A. The approximation is not accurate because the error of the range rule of thumb's approximation is greater than 15 cm3. B. The approximation is not accurate because the error of the range rule of thumb's approximation is less than 15 cm3. C. The approximation is accurate because the error of the range rule of thumb's approximation is greater than 15 cm3. D. The approximation is accurate because the error of the range rule of thumb's approximation is less than 15 cm3.
