Please help me understand why I got this multiple choice wrong, thank you so much! :) I will medal! :>

OpenStudy (lacris):

OpenStudy (lacris):

So since it's 18-35 year olds, wouldn't it be 237/560? = 0.423 which is greater than ).05? Thus making it more likely?

OpenStudy (lacris):

What do they mean by "individuals in general" is this by the total population which is: 2249?

OpenStudy (danjs):

Yeah, they mean is the probability for 18-34 saying more likely larger or smaller than probibility of the total population (individuals in general) saying more likely

OpenStudy (danjs):

237/560 vs 1370/2249

OpenStudy (lacris):

its 237/560 right?

OpenStudy (lacris):

= 0.423?

OpenStudy (lacris):

but how does that explain why it's less likely? Does the probability have to be larger than 0.5? or 0.05? to be more likely to occur?

OpenStudy (danjs):

people in general that say more likely - 1370/2249 = .61

OpenStudy (danjs):

The 18-34 has smaller probability than people in general to say more likely.

OpenStudy (lacris):

Are​ 18- to​ 34-year-olds more likely : So they were asking for ALL of the 18-34's so it was: 0.61

OpenStudy (danjs):

Yeah all 18-34 saying more likely, 237 of them out of 560 individuals in general saying more likely, 1370 of them out of 2249

OpenStudy (lacris):

So the part where it states "than individuals in​ general" does that mean every other party so: more likely (1370) + less likely (69) + (810) neither / 2249? Which is: 0.61 - (the individual 18-34) 237/560 = 0.135?

OpenStudy (danjs):

The 18-34 are less likely, 237/560 is less than 1370/2249

OpenStudy (lacris):

OOOOH So than the individuals in general!! So compared to the 18-34 in their specific section versus, all people in 1370/2249 (everyone)?

OpenStudy (danjs):

The odds someone in general says more likely is 1370/2249

OpenStudy (danjs):

Right, the 18-34 have 237/560 odds of saying more likely the individuals in general have 1370/2249 odds of saying more likely 18-34 has less odds of saying more likely compared to people in general

Ahhh!! I see! I understand, thank you so much! :D <3 thank you for your patience!
