12. You found that the null hypothesis μ1- μ2 ≤ 100 could not be rejected at a = 0.05. If the same sample is used,which of the following is correct?
(A)H0:μ1- μ2 ≤ 95 can never be rejected at a = 0.05;
(B)H0:μ1- μ2 ≤ 105 can never be rejected at a = 0.01;
(C) H0: μ1- μ2 ≤ = 100 can never be rejected at a = 0.05;
(D) Insufficient data to claim any of the above.
