A Graphical Sequential Weibull Life Test Procedure

This paper presents a series of graphed sequential tests to be used for testing the joint hypothesis that (the Weibull shape factor)
\beta
=
\beta
0
and that (the Weibull scale factor)
\theta
=
\theta
0
. These o plans, obtained by simulating life tests on an IBM 7090 computing system, are specified for two sample sizes, five confidence levels, and six shape factors (
\beta>
0
o).
