I think you need to restart your Julia session to cancel the deprecated warnings.

Once deprecated warnings are invoked, they stick to the session even after calling `using Statistics`. So, you need to call `using Statistics` before invoking deprecated warnings.

If it still happens, can you paste all the commands from the start-up of Julia along with `versioninfo()`?

Oh, thanks.

So from the new session, call using Statistics first before any call to mean(A), then no such warning.
