Confidence interval (in one-sample t-test)

Discuss statistics related things

Hello
It is not possible to calculate a confidence interval for an average at a level other than 95%.
Is this a bug?
Sincerely
Jantonie

hmm, you're right, there's an issue here (seems to only affect the one sample t-test).

to work around, you can remove the variable Duree, and add it back again (after you've changed the confidence interval option), and it will give you the correct CI.

this will be fixed in the next release

with thanks
