The brain volumes (cm³) of 20 brains have a mean of 1184.4 cm³ and a standard deviation of 121.7 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 1377.8 cm³ be significantly high? Significantly low values are cm³ or lower (Type an integer or a decimal. Do not round)
