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. This is a small sample. Think about it. He could have sampled five duckies and if he just happened to get one of the defective ones, he would have said, oh, maybe 20% are defective.
