Hey .. I found it okay but the last question was a big WTF! I tried solving it and ended up with a calc formula where I was trying to minimize the value
And calc is not a prereq for this class so I'm pretty sure I fucked that up lol.
You know the question where you had to calculate B, everyone I talk to got an answer that was like 0.4 off ... thinking about it, I think he rounded off wrong because if you used the answer that was slightly off, you got all the rest of the calculations right (if that makes sense).
I redid it with the number he gave as an option, and it was definitely wrong lol.
Some of the T/F was shit that we didn't even learn .. wtf is a dot plot
EDIT: I just realized that I didn't read that big ass chunk of text for the regression line question, maybe it explained that x is not explanatory variable and that y is not response variable (that they are switched) .. which would mean simply plugging X and Y into B = r * Sy/Sx would be wrong ...
But that's some fucking next level trolling if he did that. That would explain why the answer on the exam was slightly off for that question.
