Answer 2

In statistics, a population is the entire pool from which a statistical sample is drawn. A population may refer to an entire group of people, objects, events, hospital visits, or measurements. A population can thus be said to be an aggregate observation of subjects grouped together by a common feature.

Unlike a sample, when carrying out statistical analysis on a population, there are no standard errors to report—that is, because such errors inform analysts using a sample how far their estimate may deviate from the true population value. But since you are working with the true population you already know the true value.
