WebJun 20, 2024 · Two-Tailed Test: A two-tailed test is a statistical test in which the critical area of a distribution is two-sided and tests whether a sample is greater than or less than a certain range of values ...
WebWe use p p -values to make conclusions in significance testing. More specifically, we compare the p p -value to a significance level \alpha α to make conclusions about our hypotheses. If the p p -value is lower than the significance level we chose, then we reject the null hypothesis H_0 H 0 in favor of the alternative hypothesis H_\text {a} H a. WebTwo-tailed hypothesis tests. A test of hypothesis where the area of rejection is on both sides of the sampling distribution. If level of significance is 0.05 of a two-tailed test, it …
