Numbers
Control 5.0%, B 5.8% → +16% relative lift.
Is it real?
5000 each, 40-conversion gap — directionally positive but borderline; likely near, not clearly past, 95%. Confirm with a significance calculator or run a few more days; don't stop early.
Rates/lift computed from your numbers; significance given as a rough figure to confirm — never overstated.
