- PARAMETERS specifies that the test is non-directional
(two-sided), the significance level uses the default 0.05 value, the population mean(s) under
testing is set to 1, and the population standard deviation is set to 0.5.
- PLOT specifies that the two-dimensional power by effect
size (or mean difference) chart displays in the output. The three-dimensional power by sample size
ratio (y-axis) and effect size (x -axis) chart also displays in the output. The vertical and
horizontal rotation settings use their default values (10 degrees and 325 degrees
respectively).
