![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.
