Your question is Statistical Significance of Lift. 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).
How do you determine if a lift in a metric is statistically significant?
Explain the hypothesis-testing process for comparing two independent proportions, including the null hypothesis, test statistic, p-value, confidence interval, and decision threshold. Use the illustrative values in the structured data to demonstrate the calculations, then distinguish statistical significance from practical significance.
