correlation is not causation.
repeat the experiment.
Without 25 observations at least we cannot draw conclusions
Depends on your dataset, confidence, and margin of error.
Assuming that 95% of billionaires will act similarly and 750-ish total billionaires in the US, if you want to have 99% confidence and 1% margin of error, you'll need a minimum sample size of around 600.
We really should be thorough. For science.
Usually I would nit pick the hypothesis you want to confirm and the math you used, but for some reason 600 sounds right.
Hmmmm... I wonder what would cause pharmaceutical prices mysteriously drop?
