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. s= n[Σ(†•×²)]-[Σ(f•x)]² n(n-1) Interval Frequency Standard deviation (Round to one decimal place as needed) 20-29 2 + 30-39 3 40-49 1 + 50-59 2 60-69 8 + 70-79 32 + 80-89 38
