The quality assurance department of a chair factory samples daily production to test for the strength of the chairs being produced. what is the population they are testing for quality?

This is one of those statistical follow-up questions and had to look for the options. Since the department of quality assurance is assessing the durability of the chairs being produced, the population that they are testing for quality is ALL THE CHAIRS THEY PRODUCED. Hope this helps.
