A recent Fox News Poll asked a random sample of 900 adults nationwide the following question: "Do you believe in God?". At the same time CNN posted the same question on their website as a "Quick Vote" question where anyone who wants to can cast their vote. Here's the result of both surveys:
Yes No Sample Size
CNN Quick Vote 52% 48% 7362
Fox News Poll 92% 8% 900
a) As you can see, the results of the 2 polls are quite different. Which survey gives a better estimate of the percentage of all US adults who would say they believe in God?
CNN Quick Vote survey because it has more people.
Fox News Survey because Fox claims to be fair and balanced.
The Fox News Survey because the people were randomly drawn from adults nation-wide.
