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

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.

Answer 10

No, your sample is not random if you are only polling students who buy hot lunch on a particular day. A random sample is one in which each member of the population has an equal chance of being selected. By limiting the sample only to those students who buy hot lunch on a specific day, you haven't included the opinions of those students who bring their own lunch or eat off-campus, so your sample won't accurately represent the opinions of the entire student population. To obtain a random sample, you should consider polling students from different grade levels or at different times on different days.
