Answer 1

It is reasonable to use the entire population in the situation where a scientist wants to determine the average age of the trees in a national forest. Since the population in this case (the age of all trees in the national forest) is likely manageable and relatively small, it may be feasible to collect data from the entire population rather than just a sample.
