Quizplus · Accepted Answer

The sampling frame is the list of AARP members because this is the source from which the sample was selected. The sampling frame always refers to the population from which the sample is drawn, and in this case it is the AARP members who are 50 years of age or older. The percentage of drivers who intend to purchase a hybrid in the next two years is the sample statistic, not the sampling frame. Option D is incorrect because it describes the research question rather than the sampling frame. Option A is incorrect because it is the population of interest, not the sampling frame. Option B is incorrect because the estimated percentage is a sample statistic and not the sampling frame.
