Since the research question extends to not only the students tested, but to people found around the world, I don't think such a statement could be made with such a small study. The fact that the study was done in a "moderate-sized city in the western United States" does not nessecarily mean the study even represents students in America in general, since a country that big will have diverse cultures, spanning from city to city.
HOwever, if this study was done in other countries as well as other parts of the United States, it might give a better generalization to make our assumptions on.
