Register95% CI for a test on difference [General Statistics]
Dear David, Dear ElMaestro!
Totally correct.
The equivalence test is TOST (two-one-sided tests) each with alpha=0.05 which is operationally equivalent
to 1-2*alpha CI.
Difference test has a two-sided alternative HA, and thus is dual to an 1-alpha CI, i.e. 95%CI if you set alpha to 0.05.
The 95% CI of the above cited example is
❝ The model is build the same way whether you are assessing difference in means or bioequivalence. The hypothesis are, however, different.

The 95% CI of the above cited example is
95% CI = 89.86 ... 100.61% (contains 100%)
so no significant treatment effect, same conclusion as via the ANOVA p-value.—
