Okay, so rejecting A now makes more sense to me after reading carefully.
If it were true the percentage of the first finding would be >50%.
So now we'll have to go through the reason for rejecting the others to see where the flaw is.
Also I think we need to be looking more closely at what the findings (if true) tell us:
If you're a subscriber then you're more likely to buy if you're OVER 35, but generally, most orders are place by under 35s. So something's going on here such that there's some special characteristic of being a subscriber that interacts with your age and buying decision.
B I still don't see how what's going on NOW has anything to do with this.
C can't be true. It would satisfy (1) but negate (2).
D Dollar amount is still a scope thing.E Ahhhh look at this. I was thrown off because it doesn't talk about age BUT, looking at the characteristics of the findings we see that this statement fits well with the phenomenon we observe. (2) says that most ads were bought by under 35s, yet only 30% of under 35 subscribers bought ads. So there's gotta be a lot of non-subscribed under 35's buying ads! Bingo Bango Boom. If that's not the OA I'll probably implode.Edit: by "buying ads" I meant placed an order or whatever. You know what I mean.
