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∑f•x2−∑(f•x)2 n(n−1) Interval 20-26 27-33 34-40 41-47 48-54
55-61 62-68 Frequency 1 4 5 1 9 37 39
Standard deviation= ?
(Round to one decimal place as needed.)
