Find the standard deviation, s, of sample data summarized in the frequency distribution table given below 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 deviation to the standard deviation obtained from the original list of data values, 9.0. S= n(n - 1) Interval 30-36 37-43 44-50 51-57 58-64 65-71 Frequency 3 19 41 21 6 4 Standard deviation = (Round to one decimal place as needed.)
