Find the p-value of the test statistic
WebDec 13, 2024 · What is the P-value? 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. WebMar 26, 2024 · Compute the p -value of the test. Compare the value computed in Step 4 to significance level α and make a decision: reject H0 if p ≤ α and do not reject H0 if p > α. Formulate the decision in the context of the problem, if applicable. Example 8.3.2 The total score in a professional basketball game is the sum of the scores of the two teams.
