The National Academy of Science reported that 37% of research in mathematics is published by US authors. The mathematics chairperson of a prestigious university wishes to test the claim that this percentage is no longer 37%. He has no indication of whether the percentage has increased or decreased since that time. He surveys a simple random sample of 221 recent articles published by reputable mathematics research journals and finds that 98 of these articles have US authors. Does this evidence support the mathematics chairperson’s claim that the percentage is no longer 37%? Use a 0.05 level of significance.
