The brain volumes (cm) of 20 brains have a mean of 1192.2 cm° and a standard deviation of 129.3 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 1430.8 cm° be significantly high?
