1 7, 3.2.37 HW Score: 87.96%, 15.83 of 18 points Part 1 of 2 Points: 1 of 2 S Find the standard deviation, s, of sample data summarized in the frequency distribution table 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, 11.1.
