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

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.
