Abstract:

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.
