A consulting firm gathers information on consumer preferences around the world to help companies monitor attitudes about health, food, and healthcare products.

In a random sample of 810 respondents, 433 of 661 people who live in urban environments agreed (either completely or somewhat) with thatstatement, compared to 75 out of 149 people who live in rural areas. Based on this sample, is there evidence that the percentage of people agreeing with the statement about regional preferences differs between all urban and rural dwellers? Write the appropriate hypotheses to conduct a hypothesis test. Let p1 be the proportion of people living in urban environments that agree with the statement.
