    No. Your sample should include several days. You'll probably get different answers on pizza day than on mystery meat day.

  4. You're being asked which of those is a random sample.

    If you only poll kids who are eating school lunch on a specific day, you don't have a random sample. You haven't talked with anyone who is not eating hot lunch. Perhaps many of them hate the lunch, while those who are eating it like the lunch.
