The National Academy of Science reported that 44 % 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 44 % . He has no indication of whether the percentage has increased or decreased since that time. He surveys a simple random sample of 261 recent articles published by reputable mathematics research journals and finds that 96 of these articles have US authors, Does this evidence support the mathematics chairperson's claim that the percentage is no longer 44 % ? Use a 0.05 level of significance. Step 3 of 3: Draw a conclusion and interpret the decision. Answer 2 Points Keypad Keyboard Shortcuts We fail to reject the null hypothesis and conclude that there is insufficient evidence at a 0.05 level of significance that the percentage of research in mathematics published by US authors has changed.
