WebUse a table of cumulative areas under the normal curve to find the z-score that corresponds to the given cumulative area. If the area is not in the table, use the entry closest to the area. If the area is halfway between two entries, use the z-score halfway between the corresponding z-scores. WebMay 7, 2024 · To find the p-value, we can simply locate the value -1.22 in the z table: The p-value that corresponds to a z-score of -1.22 is 0.1112. Example 2: Find P-Value for a Right-Tailed Test. Suppose we conduct a right-tailed hypothesis test and get a z-score of 1.43. What is the p-value that corresponds to this z-score?
