| Abstract: | Summary We deal with double sampling plans by variables for a one-sided specification limit when the quality characteristic is normally
distributed with unknown standard deviation. An algorithm is presented that allows to calculate the OC of the sampling plans
proposed by Bowker and Goode (1952). We give several examples. Furthermore, it is shown that the algorithm carries over to
calculating the OC of the double-stage t-test.
