4 Attitudes toward recycled products. Recycling is supposed to save resources. Some people think recycled products are lower in quality than other products, a fact that makes recycling less practical. People who actually use a recycled product may have different opinions from those who dont use it. Here are data on attitudes toward coffee filters made of recycled paper among people who do and dont buy these filters:10 Think the quality of the recycled product is Higher The same Lower Buyers 20 7 9 Nonbuyers 29 25 43 (a) Find the marginal distribution of opinion about quality. Assuming that these people represent all users of coffee filters, what does this distribution tell us? (b) How do the opinions of buyers and nonbuyers differ? Use conditional distributions as a basis for your answer. Can you conclude that using recycled filters causes more favorable opinions? If so, giving away samples might increase sales.
