Question 409984: If the decision is to reject the null hypothesis of no difference between two population parameters, z distribution at the .01 significant level, what is the correct statement of the alternate hypothesis and rejection region?
A. µ1 ≠ µ2 ; z > 2.58 and z < negative 2.58
B. µ1 ≠ µ2 ; z > 1.96 and z < negative 1.96
C. µ1 > µ2; z > 2.33
D. µ1 > µ2; z < negative 2.33

You are rejecting the Ho of equality.
So Ha is u1 is not equal to u2

This is a 2-tail test with 0.005 in
each tail.

invNorm(0.005) = -2.58
