The brain volumes (cm cubed) of 20 brains have a mean of 1051.4 cm cubed and a standard deviation of 123.2 cm cubed. 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 1247.8 cm cubed be significantly high?
