How to set alpha in Test mean

Dear community,

in Distributions platform I can test the mean, but how to change the alpha level (e.g. from 95% confidence to 99% confidence). I know in oneway there is a "set alpha level" in the red triangle, but couldn't find it in Test Mean.

Thanks

If you already have a distribution and want to test the mean, the significance level is irrelevant. The Test Mean functionality shows everything you need (i.e. the entire distribution including the location of the hypothesized mean) and lets you open p-value as well as power animations.
