The brain volumes (cm³) of 50 brains vary from a low of 904 cm³ to a high of 1486 cm³. a. Use the range rule of thumb to estimate the standard deviation. The estimated standard deviation is cm³ (Type an integer or a decimal) Work/Technique Submission: 3 pts will be assessed in your submission b. Compare the result from part "a" to the exact standard deviation of 174.4 cm³ assuming the estimate is accurate if it is within 15 cm³. (Type your answer as an uppercase letter that corresponds to your choice) A The approximation is accurate because the error of the range rule of thumb's approximation is greater than 15 cm³. B The approximation is accurate because the error of the range rule of thumb's approximation is less than 15 cm³. C The approximation is not accurate because the error of the range rule of thumb's approximation is greater than 15 cm³. D The approximation is not accurate because the error of the range rule of thumb's approximation is less than 15 cm³.
