Fig. 5From: COVID-19 prevalence estimation by random sampling in population - optimal sample pooling under varying assumptions about true prevalenceCentral 95% estimates of \( \hat{p} \) with a test with sensitivity (η) 0.70 and a specificity (θ) of 0.99 under different combinations of total number of samples and level of sample pooling. a: p = 0.001; b: p = 0.003; c: p = 0.01; d: p = 0.03; e: p = 0.10Back to article page
