Answer: TRUE.
In statistics the term population denotes all the members on whom it is wanted to make an study and lead some conclusions.
On the other hand, sample is a subset from the population which is the set of members of the populations which is selected to measure the variables and the results will be extrapolated to the total population. There are some conditions necessesary to pretend that the conclusions derived from the sample are valid for the population.
For example, if you want to learn a about the characteristics of the students of a school, the population is all the students of the school, but you will likely will select a radom sample of students fo make the study.
