Suppose we have taken independent, random samples of sizes n1 = 8 and n2 = 8 from two normally distributed populations having means µ1 and µ2, and suppose we obtain , (something goes  here but I cant type it) , s1 = 5, s2 = 4. Use critical values to test the null hypothesis H0: µ1 − µ2 < 20 versus the alternative hypothesis Ha: µ1 − µ2 > 20 by setting α equal to .10, .05, .01 and .001. Using the equal variance procedure, how much evidence is there that the difference between µ1 and µ2 exceeds 20? (Round your answer to 3 decimal places.)

  t = ___________
  ______________ H0 at α = 0.1, 0.05, .01 and, 0.001, _____________  evidence.
