      The current summary and description of ZTEST is inaccurate.
      This may be of help for understanding:
      http://wiki.services.openoffice.org/wiki/Documentation/How_Tos/Calc:_ZTEST_function
      See also http://qa.openoffice.org/issues/show_bug.cgi?id=90759

      First proposal was to change the summary to
      "Calculates the probability of observing a z-statistic greater than the one computed based on the sample."
