The 143 heights of males from a data set of body measurements vary from a low of 155.0 cm to a high of 190.8 cm. Use the range rule of thumb to estimate the standard deviation s and compare the result to the standard deviation of 9.63 cm calculated using the 143 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 accurate because the error of the range rule of thumb's approximation is 1.2 cm
