Question

Quizplus · Accepted Answer

A statistical significance test is used to determine if the null hypothesis should be rejected based on the level of significance chosen (usually 0.05 or 0.01). It involves calculating a test statistic (such as a t-statistic or z-score) and comparing it to a critical value based on the chosen level of significance and degrees of freedom. If the test statistic is less than the critical value, the null hypothesis is not rejected. If the test statistic is greater than the critical value, the null hypothesis is rejected in favor of the alternative hypothesis.
