The brain volumes (cm cubed) of 50 brains vary from a low of 902 cm cubed to a high of 1478 cm cubed. Use the range rule of thumb to estimate the standard deviation s and compare the result to the exact standard deviation of 175.2 cm cubed, assuming the estimate is accurate if it is within 15 cm cubed.
