Which of the following is an example of a random sampling?
the school newspaper asks teachers in that middle school how they feel about the behavior of twelve year old boys.
the manager of a restaurant asks customers their opinion on a new salad dressing.
a national survey company picks one phone number from each area code in america to call and ask for an opinion on current political issues.
migrant workers are surveyed on their opinion of mandatory health insurance for companies.

I'm going to go with the following: A national survey company picks one phone number from each area code in America to call and ask for an opinion on current political issues.

The reason I went with this option is because in statistic terms people are chosen from a larger group making them a subset. The individuals are being chosen randomly but yet the individuals all have the same likelihood  of being chosen as anyone in the subset group.

Hopefully this helps and makes sense.

1. read the following excerpt from franklin d. roosevelt's "fireside chat 19":

on the other side of the picture, we must learn also to know that guerilla warfare against the germans in, let us say serbia or norway, us; that a successful russian offensive against the germans us; and that british successes on land or sea in any part of the world strengthen our hands.

remember always that germany and italy, regardless of any formal declaration of war, consider themselves at war with the united states at this moment just as much as they consider themselves at war with britain or russia. and germany puts all the other republics of the americas into the same category of enemies. the people of our sister republics of this hemisphere can be honored by that fact.  

the true goal we seek is far above and beyond the ugly field of battle. when we resort to force, as now we must, we are determined that this force shall be directed toward ultimate good as well as against immediate evil. we americans are not destroyers — we are builders.
