Question:

The brain volumes (cm3) of 50 brains vary from a low of 946 cm cube cm3 to a high of 1446 cm cube cm3. Use the range rule of thumb to estimate the standard deviation s and compare the result to the exact standard deviation of 154.6 cm cube cm3​, assuming the estimate is accurate if it is within 15 cm cube cm3.
