Question

A particular country has 55 total states. If the areas of 35 states are added and the sum is divided by 35, the result is 191,374 square kilometers. Determine whetherthis result is a statistic or a parameter.Choose the correct answer below.O A. The result is a statistic because it describes some characteristic of a sample.B. The result is a parameter because it describes some characteristic of a sample.OC. The result is a parameter because it describes some characteristic of a population.D. The result is a statistic because it describes some characteristic of a population.

Answer 1

Lets reminde the differences between parameter and statitics:

A parameter is a number describing a whole population (e.g., population mean), while a statistic is a number describing a sample (e.g., sample mean).

In our case, we took a sample of 35 states and fond the average area of each state, so this number describe our sample of 35 states, so is a "statistic".
