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:)
Homework Answers
Solution: Given standard deviation = 171
The range of values is from 922cm^3 to 1494 cm^3
range rule : s = range / 4
s = (1494-922)/4
s = 572/4
s = 143
we note that the estimated standard deviation of 143 is lower than the true standard deviation of 171
