I assume you use those 3-neon lights receptacle tester like this:

If it says hot ground reversed, it probably is.

Forgot to add, assuming that when you did this test you unplug every other
devices and turned off everything on this circuit. Otherwise, it may mean an
open neutral.

It's easy to tell whether you have open neutral or hot-neutral reversed.
Plug in a low power device like a night light at the same time you have the
outlet tester plugged in. If the night light lights up, it's not open
neutral.
