A local paper wants to collect a sample to help predict the next election. ... . They want to take a sample of 1,500 voters. . They randomly select 500 Republicans, 500 Democrats, and 500 Independents. Is this an example of a simple random sample of registered voters in North Carolina? Yes, each registered voter had an equal chance of being selected. No, each group had the same number of voters. This would be impossible with a simple random sample. No, not all registered voters had an equal chance of being selected. Yes, since there are equal numbers in each of the three categories then it is a simple random sample.
