WebThe first step is to state the null hypothesis and an alternative hypothesis. Null hypothesis: μ 1 - μ 2 = 0. Alternative hypothesis: μ 1 - μ 2 ≠ 0. Note that these hypotheses constitute a two-tailed test. The null hypothesis will be rejected if the difference between sample means is too big or if it is too small. WebThe variables sampling approach has a strict normality assumption, but requires fewer samples. In this blog post, I'll focus on the attribute approach. Attribute Sampling. A simple formula gives you the sample size required to make a 95% confidence statement about the probability an item will be in-spec when your sample of size n has zero defects.
