Question

WILL MEDAL AND FAN FOR THE FIRST TO HELP ME OUT!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!







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 at the school cafeteria on a particular day. Is your sample random? Explain.

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

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