WebDec 13, 2024 · In statistical hypothesis testing, the p-value (probability value) is a probability measure of finding the observed, or more extreme, results, when the null hypothesis of a given statistical test is true. The p-value is a primary value used to quantify the statistical significance of the results of a hypothesis test. WebRecognizing that the first part of the right-hand side of the equation is the inverse of P/T gives: So, it turns out that P/T is related to the process capability index, Cp. The value of P/T will remain constant for a set of specifications and a given measurement system. Now, suppose you improve the process, i.e., decrease the product variation.

WebThe two-tailed p-value is P > t . This can be rewritten as P (>3.7341) + P (< -3.7341). Because the t-distribution is symmetric about zero, these two probabilities are equal: P > t = 2 * P (< -3.7341). Thus, we can see that the two-tailed p-value is twice the one-tailed p-value for the alternative hypothesis that (diff < 0).
