But the larger your sample, the higher probability that your estimate is close to the actual parameter for the population. And 10 in this is just too low. In future videos, we'll talk about how you can estimate the probability or how you can figure out whether your sample seems sufficient. But for this one, for what Roy did, I don't think 10 duckies is enough. If he sampled maybe 100 duckies or more than that and he found that 10% of them were defective, well, that seems less likely to happen just purely due to chance. Let's do a few more of these. Actually, I'll do those in the next videos.
