Question: 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 readable versions with longer versions with the longer versions available online. Is this ok with authors? The journal asked a random sample of 104 of its recent authors several questions. One said: "Should the journal continue using this system?" In the sample, 72 said yes. What proportion of all authors would say yes if asked? Estimate with 95% confidence. Do the data proved good evidence that more than 2/3 of authors support continuing this system? Answer both questions with appropriate inference methods.
