Question: Find the standard deviation of sample data summarized in a frequency distribution table by using the formula below, where x represents the class midpoint, f

Find the standard deviation of sample data summarized in a frequency table by using the formula below, where x represents the class midpoint, f represents the class frequency, and n represents the total number of sample values. Also, compare the computed standard deviations to these standard deviations obtained by using Formula 3-4 with the original list of data values: (Exercise 37) 11.1 years; (Exercise 38) 9.0 years; (Exercise 39) 13.4; (Exercise 40) 9.7years.
