Posted by Susie on Tuesday, August 6, 2013 at 3:50pm.

A study was conducted to examine the peer review process. The investigators hypothesized that reviewers suggested by authors would give more favorable reviews than reviewers picked by journal editors. They obtained data on 40 manuscripts that had been reviewed by 1 author-suggested and 1 editor-suggested reviewer. They obtained the following results:

Author-suggested reviewer
Editor-suggested reviewer Favorable (accept/revise) Unfavorable (reject)
Favorable (accept/revise) 10 1
Unfavorable (reject) 9 20
Calculate the exact two-sided p-value associated with this outcome (calculate the exact binomial probability).
