Your question is Significant Result, Small Business Impact. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
You ran an experiment on a product change and the analysis says the result is statistically significant. But the observed lift is tiny, and you are not sure it matters for the business.
How would you explain a statistically significant result that has very little business impact?
