Question

Sanjay called random phone numbers in his state until he reached 1,000 people. Among those who answered the phone, 385 consented to participate in Sanjay's survey.

Is this a random sample of the people in the state?

Answer as Yes or No

Answer 1

Answer: NO

Explanation:

This is because if you think about it, only the people that want to do the survey do it. Those who dont want to do it dont have to. This makes it voluntary. Any time the surveyed person gets to choose if they can do it it is voluntary. Furthermore, If it is voluntary it can usually represent all of the different peoples. But in this case, the shy people dont get a say because they would choose to not survey. So the shy people would not be represented. That is why this isn't random.
