Figure 2:

Confidence intervals give an indication of the reliability of a germination test result (proportion or percentage germination) as an estimate of the whole seed lot viability. (A–D) Ninety-five per cent modified Jeffrey's confidence intervals [Brown et al., 2001; calculated using EpiTools (AusVet Animal Health Services, 2016)] for sample sizes of 25, 50, 100 and 200 seeds and germination results ≥75%. (E–H) The predicted survival curves for rice seeds stored at 7% moisture content and 3°C with initial viability of 96 (E and F) or 95% (G and H) or the lower and upper limits of the 95% confidence intervals of these proportions for the corresponding sample size (as indicated in the upper graphs).
