The 168 heights of males from a data set of body measurements vary from a low of 156.0 cm to a high of 194.6 cm. Use the range rule of thumb to estimate the standard deviation s and compare the result to the standard deviation of 10.74 cm calculated using the 168 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 1.8 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.)
