Find the standard deviations of sample data summarized in the frequency distribution table below by using the formula below, where x represents
the class midpoint 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. 11.1.
