Use critical values to test the null hypothesis H0: 1 2 20 versus the alternative

Question:

Use critical values to test the null hypothesis H0: μ1 – μ2 ≤ 20 versus the alternative hypothesis H0: μ1 – μ2 > 20 by setting α equal to .10, .05, .01, and .001. How much evidence is there that the difference between μ1 and μ2 exceeds 20?
