 Paper 28

The surviving four-page PDF does not include the separate S-Plus output sheets. Consequently it does not identify several fitted formulas, coefficients, test results or survival-table crossing times. The solutions below derive the identifiable results and explain the output interpretation; numerical conclusions requiring those absent sheets are distinguished explicitly from what the printed information establishes.

The official PostScript edition has also been rendered and checked: it has the same four pages and contains no separate output sheets.
