I am confused on how to solve this.

Exercise 11-6. Using the hypothetical data in table 11-3, calculate the sample variance and sample standard deviation. Next, calculate the population variance and the population standard deviation using the same data. After completing your calculations, explain in plain English Why the answers are different for the sample and population equations. How and why are the formulae different?
