✅ Best-Case Scenario

If non-respondents are similar to respondents (k=1)

📊 Statistical Confidence

Assuming all possible bias levels (from no bias to maximum bias), the true support level is between 58.1% and 80.6%.

🔍 Adjusted for Non-Response Bias

Assuming non-respondents are 3× more likely to say “no”

⚠️ Worst-Case Scenario

All non-respondents oppose (k>6.1)

Your survey’s “yes” majority is statistically robust. Even in the most extreme scenario assuming unprecedented levels of bias, support remains above 53%.
