Q: 15

than campaign strategy B in terms of additional sales. The campaigns both ran at the same time
against mutually exclusive portions of the advertiser's customer base.
What is the null hypothesis of the test design?

Option C. had exactly this on my exam. Confirms what I saw.
C vs B. I get why some would say B since "equality" is a classic null, but for this setup C is better because you're testing if A's lift is at least as much as B's, not just identical. Pretty sure test design guides lean toward C here.
