Question 2 • Math Models A
A sample of 30 is small compared with the 5,200 registered voters, so its results may vary considerably from sample to sample and can lead to unreliable or false inferences. Randomly choosing voters is a sound sampling method, not a reason the sample is invalid. A larger sample generally gives more reliable information, while 30 is not too large to make inferences.
