A poll asked random samples of adults in 2016 and 2018 if they were satisfied with the quality of the environment. In2016, 535 were satisfied with the quality of the environment and 443 were dissatisfied. In2018, 470 were satisfied and 507 were dissatisfied. Determine whether the proportion of adults who are satisfied with the quality of the environment has declined. Use a 0.10 significance level.

Let p1 represent the population proportion of adults in 2016 who were satisfied with the quality of the environment and let p2 represent the population proportion of adults in 2018 who were satisfied with the quality of the environment. Write the hypotheses for the test.
