统计假设检验在PCB实验过程中的运用研究

Research on the application of statistical hypothesis testing in the process of PCB experiment

假设检验作为统计学的组成部分,已经被引入六西格玛解决问题的系统中,并发挥着重要作用。通过假设检验,可以帮助技术人员科学的做出类似"这个问题是否真的得到了改善?"的科学决策,从而达到省时省力、少走弯路的目的。

As part of the statistics, the PC hypothesis testing as a part of the statistics has been introduced into the system of Six Sigma to solve problems, and plays an important role. Through the hypothesis testing, can help technical personnel to make a similar question whether it really has improved？ The scientific decisionmaking, in order to save time, avoid detours to.
