Tables for Comparing Two Mean-Time-Between-Failures (MTBFs) for Unequal Test Times.

摘要

Tables of critical values for carrying out the exact method of comparing two MTBFs for unequal test times are tabulated for .001, .01, .05, .10, and .20 levels of significance with the ratio of the two test times ranging from 0.1 to 5.0 by increments of 0.1 and the total failures ranging from 1 to 100. The computational formulas for the exact method used on the ARRADCOM CDC Cyber 76 Computer located at APG are presented. Examples illustrating the application of these tables are also presented.
