A sample of 10 numbers has a standard deviation of 8.756. If those same numbers were a population, what would the population standard deviation be?
A. 7.880 B. 8.307 C. 8.700 D. 9.230
Solution
Sample standard deiation = Deviation calculated / Sqrt(n-1)
Deviation calculated = 8.756 * Sqrt(10-1) = 26.268
population standard deiation = Deviation calculated / Sqrt(n) = 26.268 / Sqrt(10) = 8.307
