the brain volumes (cm3) of 20 brains have a mean of 1103.2 cm3 and a standard deviation of 127.5 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 1308.2 cm3 be significantly high? Significantly low values are blank cm3 or lower. Type an integer or a decimal. Do not round. cm3 is cm to the 3rd power
