WebEquivalence assay is introduced and SET POWER your illustrated fork determining sample size for noninferiority studies. Noninferiority tests for fractions and means are conducted using PROC FREQ and PROC TTEST. WebCompute power. The power of the test is the probability of rejecting the null hypothesis, assuming that the true population proportion is equal to the critical parameter value. Since the region of acceptance is 0.734 to 1.00, the null hypothesis will be rejected when the sample proportion is less than 0.734.
