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

Correct option the value reported represent the mean for all the individuals in the population of interest and for this reason represent a parameter.

Step-by-step explanation:

For this case we know that the average age of men who had walked on the moon was 39 years, 11 months, 15 days.

So then we need to assume that this value was calculated from the average of all the mean who walked on the moon, so then we have a population represented by a parameter.

And let's analyze one by one the possible options given:

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

Correct option the value reported represent the mean for all the individuals in the population of interest and for this reason represent a parameter.

B. The value is a parameter because the men who had walked on the moon are a sample.

The value represent a parameter but the reason is not because represent a sample, is a parameter because represent the population of interest.

C. The value is a statistic because the men who had walked on the moon are a sample.

False the men who had walked on the moon are a population since they know the information about the men who walked on the moon and not represent a sample for this case.

D. The value is a statistic because the men who had walked on the moon are a population.

False the men who had walked on the moon are a population since they know the information about the men who walked on the moon, and if is a population then can't be a statistic.
