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 work on a customer communication flow where a message was changed to better explain a next step in the journey. Early results suggest conversion may have improved, but the team wants a rigorous read before deciding whether to roll it out more broadly.
How would you analyze whether the communication change improved conversion, and what evidence would you need before calling it a win?
