Quizplus · Accepted Answer

A test statistic is a numerical quantity computed from the data of a sample and is used in reaching a decision on whether or not to reject the null hypothesis. Option A, significance level, is a value chosen before conducting a hypothesis test to define the criteria for rejecting the null hypothesis. Option B, critical value, is the value used in hypothesis testing to determine whether to reject the null hypothesis. Option D, parameter, is a numerical characteristic of a population, rather than a statistic computed from a sample.
