Answer: B. The result is a statistic because it describes some characteristic of a sample.

Explanation: Statistics and Parameters are similar in that they are both numerical values that show the characteristic of a given group.

They differ in that the group whose characteristics they show differ. Statistics describe the characteristic of a sample while Parameters describe the characteristic of a population. In this case if the characteristic being measured is the whole country or all the 40 states, the value would be a parameter.
