If the 95% CI for the difference in conversion rates between two designs spans zero (e.g., -0.5% to +1.5%), what is the conclusion regarding the difference?
If the 95% CI for the difference in recovery times is (2.1 days to 4.5 days), what is the appropriate decision regarding a null hypothesis of zero difference?
