small p-value means that your data would be surprising under the null hypothesis, which counts as evidence against it. This tool converts a z-score (the standard-normal test statistic) into a p-value — the probability of observing a result at least as extreme as yours if the null hypothesis is true. The left-tailed value is P(Z ≤ z), the right-tailed value is P(Z ≥ z), and the two-tailed value is 2 × P(Z ≥ |z|) — double the smaller tail. This tool applies to z-tests and large-sample approximations.Choose a z-score of 1.96 and click on the "Worked" button.Choose a z-score of 1.96 and click on the "Worked" button.Choose a z-score of 1.96 and click on the "Worked" button.Choose a z-score of 1.96 and click on the "Worked" button.Choose a z-score of 1.96 and click on the "Worked" button.Choose a z-score of 1.96 and click on the "Worked" button.Choose a z-score of 1.96 and click on the "Worked" button.Choose a z-score of 1.96 and click on the "Worked" button.Choose a z-score of 1.96 and click on the "Worked" button.Choose a z-score of 1.96 and click on the "Worked" button.Choose a z-score of 1.96 and click on the "Worked" button.Choose a z-score of 1.96 and click on the "Worked" button.Choose a z-score of 1.96 and click on the "Worked" button.Choose a z-score of 1.96 and click on the "Worked" button.Choose a z-score of 1.96 and click on the "Worked" button.Choose a z-score of 1.96 and click on the
