esti 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 lest 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 jesti uesti [E(x)]-[Z(x)] S = n(n - 1) west Interval 20-26 27-33 34-40 41-47 48-54 55-61 uesti Frequency 3 25 45 16 8 Quest Quest Standard deviation = (Round to one decimal place as needed.)
