Find the standard deviation, s, of sample data summarizedin the frequency distribution table given below by using theformula below, where x represents the class midpoint, frepresents the class frequency, and n represents the totalnumber of sample values. Also, compare the computed standarddeviation to the standard deviation obtained from the original listof data values,
