28. You are surveying students to find out their opinion of the quality of food served in the school cafeteria. You decide to poll only those students who buy hot lunch on a particular day. Is your sample random? Explain.






29. Ira wants to determine the fast–food restaurant preferred by the majority of twelve–year–olds in his town. He decides to question all the twelve–year–olds who leave a particular hamburger restaurant. Is this a random sample? Explain.

    28. Of course it isn't random. Students who buy hot lunch probably like it.

    29. No, it's not random. Why do you think it isn't?
