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

Short Answer

In general, before an academic publisher agrees to publish a book, each manuscript is thoroughly reviewed by university professors. Suppose that the Duxbury Publishing Company has recently received two manuscripts for statistics books. To help them decide which one to publish both are sent to 30 professors of statistics who rate the manuscripts to judge which one is better. Suppose that 10 Professors rate manuscript 1 better and 20 rate manuscript 2 better. Can Duxbury conclude at the 5% significance level that manuscript 2 is more highly rated than manuscript 1?
