A polling firm wants to contact a random sample of people likely to vote in an upcoming nation-wide election. They will use a random digit dialer to generate and call phone numbers at random, so the poll will include people with landlines, unlisted numbers, and mobile phones. The random digit dialer skips invalid phone numbers. If a person doesn't answer a call, the dialer will try one more time, and then skip that number. When a person does answer, a pollster asks a set of initial questions -such as the person's age and whether or not they voted in previous elections-to see if they are likely to vote in the upcoming election. If they are eligible and likely to vote, the pollster will then ask a series of questions about the election. Which of the following is not a potential source of bias in their poll? Choose 1 Some people might refuse to share their personal information over the phone. B People who are likely to vote but don't have a telephone are excluded from the poll. Some people will not answer calls from an unfamiliar caller. D The poll excludes people too young to vote. Some people might say they are registered and suggest they are likely to vote when they really aren't. 6 of 7
