摘要

This article uses the power analysis method for the above purpose for both one-and two-sample problems. The asymptotic power functions and the corresponding formulae are derived for one-and two-sided tests using large-sample normal approximation. The asymptotic and exact powers are compared and the ratio of sample sizes under parallel model and the design of direct questioning are reported. The sample sizes for the parallel design are numerically compared with those required (Ref. 3). Two theoretical justifications and a real example are also provided. (14 refs.)
