Quizplus · Accepted Answer

Comparing the level of significance to the confidence coefficient is not a valid approach in hypothesis testing. The level of significance is chosen by the researcher prior to conducting the test, while the confidence coefficient is a measure of the precision of the confidence interval estimate. The other approaches (comparing the confidence interval estimate, p-value, or test statistic to their respective values) are valid methods in hypothesis testing.
