Question Help 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. 4 s= " [ E (F. x 2) ] - [ [(. x ) ] 2 n (n - 1 ) Interval 20-29 30-39 40-49 50-59 60-69 70-79 80-89 Frequency CO 32 37 Standard deviation = (Round to one decimal place as needed.)
