One-sided probabilities of significance for a one-sample test of the change from baseline at 2-years under the null and the alternative hypotheses (μ₂ = 0 or 1, respectively), with variance ${\sigma }_2^2=20$, for a single sample of n = 100 with 30% missing that are replaced by values at 1-year with mean μ₁ ranging from −1 to 2 and variance ${\sigma }_1^2=10$, 20, 30. The correct probabilities with no missing data are designated by the dots.
