The manager is interested in determining the satisfaction level of customers who have purchased a DVD recorder made by the company over the past 12 months. Therefore, the population of interest is all the customers who have bought a DVD recorder made by the company over the past 12 months. Option A includes all the customers who have ever bought a DVD player made by the company, which is a broader population than the one of interest. Option C includes all the customers who have used a DVD player over the past 12 months, which includes customers who have not purchased a DVD recorder made by the company. Option D includes only customers who have bought a DVD player made by the company and brought it in for repair, which is a subset of the population of interest.
