K The brain volumes (cm) of 20 brains have a mean of 1106.4 cm and a standard deviation of 129.4 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 1335.2 cm be significantly high? Significantly low values are cm cm or lower. (Type an integer or a decimal. Do not round.)
