Math Problem Statement
he 162 heights of males from a data set of body measurements vary from a low of 151.0cm to a high of 193.3193.3 cm. Use the range rule of thumb to estimate the standard deviation s and compare the result to the standard deviation of 12.73 cm calculated using the 162 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 1.11.1 cm. Question content area bottom Part 1 Use the range rule of thumb to estimate the standard deviation s. sequals=enter your response here cm (Type an integer or decimal rounded to two decimal places as needed.)
