WebJan 24, 2024 · Many hypothesis tests in statistics result in a z-test statistic. Once we find this z-test statistic, we typically find the p-value associated with it. If this p-value is less than a certain alpha level (e.g. 0.10, 0.05, 0.01), then we reject the null hypothesis of the test and conclude that our findings are significant. WebJun 6, 2024 · To find out if this test statistic is statistically significant at some alpha level, you have two options: Compare the test statistic t to a critical value from the t distribution table.
