The brain volumes ​(cm cubedcm3​) of 20 brains have a mean of 1097.11097.1 cm cubedcm3 and a standard deviation of 126.4126.4 cm cubedcm3. 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 1299.91299.9 cm cubedcm3 be significantly​ high?
