Q: 1
An advertiser is running an A/B test on Facebook with the goal of finding whether creative strategy A
or B achieves the most conversions. What is the null hypothesis of this test design?

Its C, pretty sure. Had something like this in a mock and both conversions being zero was the null.
Double-checked the test design and pretty sure it's C (since both being zero covers the null for this setup).
Actually, isn't the null hypothesis that there's no difference between the two creatives? That would make A the right pick, not C. Null usually means equal effect, not zero conversions.
Option A, not C. Null hypothesis just means there's no difference, so A is the standard test trap.
Similar question popped up on my practice set, C.
