Question

determine whether the underlined value is a parameter or a statistic. the average age of men who had walked on the moon was 39 years, 11 months, 15 days. is the value a parameter or a statistic? a. the value is a parameter because the men who had walked on the moon are a population. b. the value is a statistic because the men who had walked on the moon are a population. c. the value is a parameter because the men who had walked on the moon are a sample. d. the value is a statistic because the men who had walked on the moon are a sample.

Explanation:

To determine if the value is a parameter or statistic, we recall: a parameter describes a population, a statistic describes a sample. The men who walked on the moon are the entire group (population) of such men. So the average age here describes the population, making it a parameter. Option A states this correctly.

Answer:

A. The value is a parameter because the men who had walked on the moon are a population.
