The brain volumes (cm°) of 20 brains have a mean of 1125.3 cm° and a standard deviation of 127.2 cm°. 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 1339.7 cm° be significantly high? cm3 Significantly low values are (Type an integer or a decimal. Do not round.) cm or lower.
