A state health department surveys 800 hospitals about surgical error reporting procedures. Response rate is 60% (480 respondents). The department uses poststratification adjustment: hospitals in rural counties (350 total) report 25% compliance; urban hospitals (450 total) report 45% compliance. Within respondents, the split was rural n=192 (30% compliance) and urban n=288 (48% compliance). What is the poststratified estimate of state-wide compliance?
