requency distribution tablé bélów 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 30-36 37-43 44-50 51-57 58-64 65-71 72-78 Frequency 4 4 18 33 36 Standard deviation =9.6 (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? O A. The computed value is significantly greater than the given value. O B. The computed value is significantly less than the given value. O C. The computed value is not significantly different from the given value,
