Question

Food preference GfK Roper Consulting gathers infor-
mation on consumer preferences around the world to

help companies monitor attitudes about health, food, andhealthcare products. They asked people in many different
cultures how they felt about the following statement:
I have a strong preference for regional or traditional
products and dishes from where I come from.
In a random sample of 800 respondents, 417 of 646
people who live in urban environments agreed (either
completely or somewhat) with that statement, compared
to 78 out of 154 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?
