Answer:
to answer this question, I need to see the paragraph, there is no paragraph that tells me what I need to look at. whenever u put it there, I will help
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.
It continues it so it’s more reasoned
