< rev 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 142 recent articles published by reputable mathematics research journals and finds that 65 of these articles have US authors. Does this evidence support the mathematics chairperson's claim that the percentage is no longer 37 % 7 Use a 0.01 level of significance. Step 1 of 3: State the null and alternative hypotheses for the test. Fill in the blank below.

Answer 2 Points Keypad Keyboard Shortcuts We reject the null hypothesis and conclude that there is insufficient evidence at a 0.01 level of significance that the percentage of research in mathematics published by US authors has changed. We fail to reject the null hypothesis and conclude that there is insufficient evidence at a 0.01 level of significance that the percentage of research in mathematics published by US authors has changed. We fail to reject the null hypothesis and conclude that there is sufficient evidence at a 0.01 level of significance that the percentage of research in mathematics published by US authors has changed.
