The 156 heights of males from a data set of body measurements vary from a low of 159.0 cm to a high of 193.7 cm. Use the
range rule of thumb to estimate the standard deviations and compare the result to the standard deviation of 10.61 cm
calculated using the 156 heights. What does the result suggest about the accuracy of estimates of s found using the range
rule of thumb? Assume the estimate is accurate if it is within 1.2 cm.
Use the range rule of thumb to estimate the standard deviation s.
S= cm
(Type an integer or decimal rounded to two decimal places as needed.)
The approximation
Vaccurate because the error of the range rule of thumb's approximation is
1.2 cm.
