The population is all seniors at Riverview High. The sample is the 100 seniors surveyed. Yep, that's exactly what we talked here. We're trying to get an indication about how all of the seniors at Riverview High feel about the food, the lunch offerings. We probably think it's impractical, or the administrators feel it's impractical to talk to everyone so they get exactly what the population thinks. So instead, they're gonna do a random sample of 100 of them. So the sample is 100 seniors who are actually surveyed.
