The 160 heights of males from a data set of body measurements vary from a low of 160.0 cm to a high of 190.5 cm. Use the range rule of thumb to estimate the standard deviation s and compare the result to the standard deviation of 7.16 cm calculated using the 160 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 1.4 cm. Use the range rule of thumb to estimate the standard deviation s. cm (Type an integer or decimal rounded to two decimal places as needed.)
