This is a sample study. How do we know that? Well, he is taking a sample from a broader population in order to estimate a parameter. The parameter is the percentage of those 100,000 duckies that are actually defective. Now, the next question is, is what kind of a conclusion can you make? Roy, since he got the shipment and he took a sample and he found that 10% of the sample was defective, he might be all up in arms and say, oh, this toy shipment from the factory, they violated this promise that the percentage of defective toys won't exceed 5% because I sampled 10 toys and 10% of those 10 toys were defective. Well, that isn't a reasonable conclusion because this is a small sample.
