h

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(n1)n[(fx2)][(fx)]2 Standard deviacion = (Round to one decimal place as needed.)
