Extracted text: 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. n(n - 1) Interval 20-26 27-33 34-40 41-47 48-54 Frequency 55-61 1 62-68 8. 4 17 35 38 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, 11.12 O A. The computed value is significantly less than the given value. O B. The computed value is not significantly different from the given value. O C. The computed value is significantly greater than the given value.
