Find the standard deviation, s, of sample data summarized in the frequency distribution table given below by using the formula below, wherex represents the class midpoint, f represents the class frequency, and n represents the total number of sample values. Also, compare the computed standard deviation to the standard deviation obtained from the original list of data values, 9.0. S= n(n- 1) Interval 20-29 30-39 40-49 50-59 60-69 70-79 Frequency 4. 19 35 24 Standard deviation = (Round to one decimal place as needed.) ng <<<< (1
