You are trying to determine what pizza shop the people in
your town like best. You and a friend spend 3 hours on a
Saturday morning asking every 10th person that walks into
Kroger. The results are clear that Vinny's NY Pizza is the
favorite.
Is this survey fair? Why or why not?

No, because they are only picking the 10th costumer. They should have done multiple.
