Webb26 sep. 2024 · For example, if 10 out of 200 tested units are defective, the defect rate is 10 divided by 200, or 5 percent. Defect rate is often stated in terms of defects per million. Defects per million reflects how many units out of 1 million would be defective. To calculate defects per million, multiply the defect rate by one million. Webbtwo-sided tests, the p-values are calculated as the probability, under the null hypothesis, of observing a likelihood ratio (or log-likelihood ratio) at least as large as the one actually observed. A numerical root finding algorithm is generally used to calculate this probability. Formula B2: Exact confidence interval
