A researcher at Ohio State University is growing bacteria in her laboratory for a study. She extracts a group of 50 cells to observe under a microscope for cell structure. Which of the following describes the population and sample?

The population is the entire group the researcher wants to study: all the bacteria growing in her lab. The sample is the smaller group selected for observation, which is the 50 extracted cells. Therefore, the correct choice is “The population is all growing bacteria in the lab, and the sample is the group of 50 extracted cells.”
