Suppose that 25% of registered voters in North Carolina are registered Republican, 55% are registered Democrat, and 20% are registered as Independent. 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. Using the information given was this a simple random sample of registered voters in North Carolina? O No, not all registered voters 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. Yes, each registered voter 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.
