Q: 3
An analyst analyzes 1,000 Facebook video campaigns and calculates there is a correlation of r = 0.6
between view duration of a campaign and additional ad recall lift. What should the analyst tell the
company about the relationship between view duration and ad recall lift?

Its D. With r = 0.6, r squared is 0.36, so 36%, but the closest match is option D at 40%. I think they rounded it up in the answer options. Agree?
Seen similar in the exam guide, D is what you'd pick here.
Hard to say, D fits best, since r = 0.6 means r squared = 0.36, and I guess they're rounding to 40%. Not perfect but closest match here.
Pretty common to see this in practice sets. D matches what you'd get from r squared (roughly 36%), and exam questions sometimes round. Official guide reviews the stats basics like this!
Option D makes sense here, even though r squared is 0.36 (so 36%), but none of the choices have that exact number. Pretty sure they rounded up to 40%. Let me know if you think I'm missing something.
