Publishing scientific papers online is fast, and the papers can be long. publishing in a paper journal means that the paper will live forever in libraries. the british medical journal combines the two; it prints short and reasonable versions, with longer versions available online. is this ok with authors?
the journal asked about a random sample of 104 of its recent authors' several questions. one question was, "should the journal continue using this system? "
in the sample, 72 said "yes."
(a) do the data give good evidence that more than two-thirds (67%) of authors support continuing this system? carry out an appropriate test to answer this question.
(b) interpret the p-values from your test in the context of the problem.
