Quizplus · Accepted Answer

A decision in a hypothesis test can be made by comparing the calculated p-value to the predetermined level of significance (usually 0.05) or by comparing the test statistic (calculated from the sample data) to the critical value (found from the appropriate probability distribution tables). Therefore, a decision can be made using either a p-value or a critical value. The sample size affects the precision of the estimation, but it does not directly impact the decision in a hypothesis test.
