Identify the target population, the accessible population (sampling frame), and the sample for the following hypothetical study. A professor who teaches three sections of a research methods class tests the hypothesis that his research methods class prepares students for a career in research. To test this hypothesis, the professor obtains a list of all students in each of his three sections and randomly selects 25 students from each section to participate in a study.
