The brain volumes (cm3 ) of 20 brains have a mean of 1070.3 cm3 and a standard deviation of 126.4cm3 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 1313.1 cm3 be significantly high?
