The brain volumes (cm) of 20 brains have a mean of 1081.8 cm and a standard deviation of 128.3 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 1378.4 cm be significantly high? Significantly low values are 825.2 cm or lower. (Type an integer or a decimal. Do not round.) Significantly high values are cm or higher. (Type an integer or a decimal. Do not round.)
