Explanation:

In statistics (a subfield of Mathematics), a sample is the specific group of individuals or items from which data is collected. Here, the survey was conducted on 15,559 residents of Texas, so this group is the sample. The residents of Texas would be the population (the entire group we want to study), and the 40% and 60% are subsets of the sample's responses, not the sample itself.
