In General, Before an Academic Publisher Agrees to Publish a Book

question 55

Essay

In general, before an academic publisher agrees to publish a book, each manuscript is thoroughly reviewed by university lecturers. Suppose that Cengage Australia publishing company has recently received two manuscripts for statistics books. To help them decide which one to publish, both are sent to 50 professors of statistics who rate the manuscripts to judge which one is better. Suppose that 20 lecturers rate manuscript A as better and 30 rate manuscript B as better.
Can Cengage Australia conclude at the 5% significance level that manuscript B is more highly rated than manuscript A?
