Abstract:

The problem under consideration is that of estimating simultaneously the differences between the means of p or 2 test treatments and the mean of a control treatment when the population variances of all p 1 treatments are known. Tables are given which permit the experimenter to find the minimal total number of experimental units, and the optimal allocation of these units among the P 1 treatments, in order to make one-sided or two-sided confidence interval estimates of the differences of interest. These intervals achieve a specified joint confidence coefficient 1-alpha for a specified allowance or yardstick associated with the common width of the intervals. The computations for these tables are based on the results of Bechhofer 1969 for one-sided comparisons, and Bechhofer and and Nocturne 1972 for two-sided comparisons. Author
