Question

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. (4 points)

Answer 1

no, I think it is bias because the surveying student just chose to poll only those students who buy hot lunch on a particular day.

Random Sampling
In random sampling, each item or element of the population has an equal chance of being chosen at each draw

Answer 2

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

Answer 3

thanks sooooo much!
