The brain volumes (cm3) of 20 brains have a mean of 1194.4 cm3 and a standard deviation of 120.7 cm3. Use the given standard deviation and the range rule of thumb to identify the limits separating values that are significantly low or significantly high. For such data, would a brain volume of 1475.8 cm3 be significantly high? Significantly low values are_____cm3 or lower
