Question 1158759
This isn't clear to me.  It is a two way test, as you have stated, but the answer choices imply that the population sd is known already, which isn't shown here. Given those choices, all of which are well-known z-values (alpha of 0.10, 0.l01, 0.01, and 0.05 respectively), the best choice would be D. 

Given the information shown, your answer is best, but presumably there is a known sd in this problem for those choices.
