The national Academy of science reported in a 1997 study that 40% of research in mathematics is published by U.S.authors. The mathematics chairperson of a prestigious university wishes to test the claim that this percentage is no longer 40%. He has no indication of whether the percentage has increased or decreased. He surveys a simple random sample of 130 recent articles published by reputable mathematics journals and finds that 62 of these articles have U.S. authors. At the 0.10 level, does this evidence support the chairperson's claim that the percentage is no longer 40%?
