17.Find the standard deviation, s, of sample data summarized in the frequency distribution table given below by using the formulabelow, 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. Standard deviation=___ Compare the computed standard deviation to the standard deviation obtained from the original list of data values, 9.0. Consider...
