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 a equal to .10, .05, .01, and .001. How much evidence is there that the difference between μ1 and μ2 is not equal to 20?
