为了保证产品的质量,要进行检查。从一批产品中随机地抽取一部分样品进行检验,并鉴定批产品的质量,这种判定产品合格与否的方法称为抽样检验。抽样检验的前提条件是工厂生产工艺稳定,产品质量水平基本一致,没有人为因素的影响。而抽样又要随机地进行。一、两类错误及接收概率由于抽样检验是从检查一部分样品质量来推断整批产品质量的状态,因此它有产生推断错误的概率,我们只是希望这种错误的概率要 In order to ensure the quality of the product, inspections should be conducted. A part of the product is randomly selected from a batch of products for inspection and the quality of the batch product is identified. The method of determining whether the product is qualified or not is called sampling inspection. The precondition for sampling inspection is that the factory’s production process is stable, and the product quality level is basically the same, and there are no human factors. The sampling must be done randomly. One and Two Types of Errors and Receiving Probability Since the sampling test infers the status of the entire batch of product quality from the quality of a part of the sample, it has the probability of producing inference errors. We just hope that the probability of such errors
