Question

A particular country has 40 total states. If the areas of all 40 states are added and the sum is divided by 40, the result is 200,979 square kilometers. Determine whether this result is a statistic or a parameter.

A. The result is a statistic because it describes some characteristic of a population.
B. The result is a statistic because it describes some characteristic of a sample.
C. The result is a parameter because it describes some characteristic of a population.
D. The result is a parameter because it describes some characteristic of a sample.

Answer 1

C) The result is a parameter because it describes some characteristic of a population.

Step-by-step explanation:

The result is a parameter because it describes some characteristic of a population.

In this case, the 40 states represent the entire population, and the result of dividing the sum of their areas by 40 gives the average area per state, which is a parameter.
