Extracted text: 3 3 The brain volumes (cm°) of 20 brains have a mean of 1075.6 cm° and a standard deviation of 122.2 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 1330.0 cm° be significantly high? ... Significantly low values are cm or lower. (Type an integer or a decimal. Do not round.)
