WebMay 7, 2024 · To find the p-value, we can first locate the value 1.43 in the z table: Since we’re conducting a right-tailed test, we can then subtract this value from 1. So our final p-value is: 1 – 0.9236 = 0.0764. Example 3: Find P-Value for a Two-Tailed Test Suppose we conduct a two-tailed hypothesis test and get a z-score of -0.84. WebThe two-tailed test gives a p-value of 0.766 (76.6%), which is much more than the p-value above and 0.10 (10%). This serves as strong evidence that the null hypothesis is true. … WebIn general, when comparing two means, the t-test is used.
