   Question

   The table below comes from a study on jurisprudence in the Netherlands. We find information about 5000 court cases (4000 + 1000). The court cases test the following hypotheses:

   $H_0$: person is innocent

   $H_1$ : person is guilty

   From the table you can see what the chosen alpha and beta were in this study.

   

   What (inexcusable) error did the researcher make?

   
   
   1. FALSE: The researcher chose alpha far too large, causing $H_0$ should be rejected far too quickly.
   2. FALSE: The investigator gets a large Type I error.
   3. TRUE: The probability of a Type II error is far too high.
   4. FALSE: The investigator has made no errors of principle.
