    Hypothesis testing. Test statistic = Critical value?

    Hi, would appreciate if anyone could answer this for me. Can't seem to find a solid answer in my textbooks.

    1) What are the chances that a test statistic "z" or "t" value could equal the critical value.


    2) If this is possible, do you accept or reject the null hypothesis then?

    Thanks a billion in advance!

    Best regards,
    Glenn

    Usually if your test statistic is equaled to the critical value, you would reject the null hypothesis.

    So your rejection region is usually in the form:  z \leq -z_{\alpha/2}, \ z \geq z_{\alpha/2} and  t \leq -t_{\alpha/2, n-1} \ t \geq t_{\alpha/2, n-1} (for a two tailed test).
