Generally, actual population parameters are unknown since the cost to perform a true census of almost any population is prohibitive. True False

True.

In most scenarios, obtaining the actual parameters of a population—such as the mean, median, or proportion—requires conducting a census, which entails surveying every individual within that population. The logistical challenges of reaching every member, along with the associated financial costs, make such comprehensive surveys impractical, especially for large or geographically dispersed populations.

Because of these limitations, researchers frequently rely on sampling methods, where a subset of the population is surveyed, to make inferences about the entire group. These inferred statistics are termed "estimates" and come with associated uncertainty. Therefore, it can be concluded that actual population parameters are typically unknown due to the prohibitive costs and complexities of performing a complete census.
