Question 1 of 8. Step 2 of 3
1/20
Correct
The National Academy of Science reported that 38 % 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 38 %. He has no indication of whether the percentage has increased or decreased since that time. He surveys a
simple random sample of 173 recent articles published by reputable mathematics research journals and finds that 79 of these articles have US authors. Does this
évidence support the mathematics chairperson's claim that the percentage is no longer 38 %? Use a 0.01 level of significance.
Step 2 of 3: Compute the value of the test statistic. Round your answer to two decimal places..
