Question: 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

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.

Interval	Frequency
20-36	1
27-33	1
34-40	1
41-47	3
48-54	16
55-61	39
62-68	33
STANDARD DEVIATION = (ROUND TO ONE DECIMAL PLACE AS NEEDED)
Consider a difference of 20% between two values of a standard deviation to be significant. How does this computed value compare with the given standard deviation, 11.1?
