The brain volumes (cm^3) of 20 brains have a mean of 1175.5 cm^3 and a standard deviation of 124.6 cm^3. Use the given standard deviation and the range rule of thumb to identify the limits separating values that are significantly high. For such data, would a brain volume of 1444.7 cm^3 be significantly high?
