Attitudes toward recycled products. Some people think recycled products are lower in quality than other products, a fact that makes recycling less practical. Here are data on attitudes toward coffee filters made of recycled paper.12
                                
(a) Find the conditional distributions of opinions on the quality of recycled products for buyers and nonbuyers. Make a graph that compares the two conditional distributions. Use your work to describe the overall relationship between people who have and haven’t bought recycled filters and their opinions on the quality of recycled products.
(b) Do buyers and nonbuyers of recycled filters differ significantly in their opinions on the quality of recycled products? State hypotheses, give the chi-square statistic and its P-value, and state your conclusion.
(c) Association does not prove causation. Explain how buying recycled filters might improve a person’s opinion of their quality. Then explain how the opinion a person holds might influence his or her decision to buy or not. You see that the cause-and-effect relationship might go in either direction.
