Your question is Statistical vs Practical Significance. 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).
Explain the difference between statistical significance and practical significance in an A/B test.
Clarify how p-values, confidence intervals, effect size, baseline performance, and the minimum detectable effect inform the distinction. Explain how you would make a ship, iterate, or do-not-ship recommendation when the result is statistically significant but too small to matter operationally, or practically meaningful but statistically uncertain.
