Quizplus · Accepted Answer

This is true. The critical values of t distribution are larger than the critical values of z distribution at the same level of significance. This is because the t distribution has fatter tails than the z distribution, which means it allows for greater variability in the sample data. Therefore, the t distribution has a wider spread of values than the z distribution, and its critical values are larger.
