At your summer with a research company, you must get a random sample of people from your town to answer a question about spending habits. Which of the following Methods is most likely to be random?
a)You survey customers at the local shopping mall
b)You survey people chosen randomly from the local phonebook
c)You survey several of you friends
d)You suvey customers at a popular resturant
The answer is B. Trust me, I just did the whole quiz! Here are the answers!
1. b
2. c
3. d
4. c
5. b
6. a, :)
My guess is A...?
People at a shopping mall usually like to shop -- so I don't think they are representative of everybody.
Several years ago I would have chosen B -- but today the majority of people only use cell phones and are not listed in phone books.
