You successfully completed statistics, and the Math Department Chair recruited you to be a tutor. It's day one on the job, and your first pupil is correcting her mistakes on a recent statistics exam. She incorrectly listed the reasons that researchers use random sampling when conducting a survey.
She wants to know why researchers should use a random sample to conduct a survey. Check all that apply.

- Random samples provide consistency and systematically favor one choice over every other choice in each survey question.
- Random sampling will provide a more representative sample of population.
- Researchers can use a random sample to draw conclusions about the population.
