The brain volumes (cm3) of 20 brains have a mean of 1118.2 cm3 and a standard deviation of 129.3 cm3 . 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 1326.8 cm3 be significantly high?
Significantly low values are ____ cm3 or lower.
Significantly high values are ____ cm3 or higher.
Significantly low values = Values below 2 standard deviation = (1118.2 - 2*129.3) cm3 or lower = 859.6 cm3 or lower
Significantly high values = Values above 2 standard deviation = (1118.2 + 2*129.3) cm3 or higher = 1376.8 cm3 or higher

the brain volumes (cm3) of 50 brains vary from a low off 922 cm3 to a high of 1494 cm3. Use the range rule of thumb to estimate the standard deviation s and compare the result to the exact standard deviation of 171 cm3, assuming the estimate is accurate if it is within 15 cm3. Preparing for a final. Really trying to master these subjects. Thanks for the help:)
