1) correlation - was negative (got this wrong)
2) confidence interval question - -.43
3) They asked you to plug numbers into the regression model, anyone else get 2.1?
cant remember other 3, but if anyone does fill in the blanks作者: thecfawannabe 时间: 2013-4-10 22:44
What about the t stat question? Was not too sure about that…think I went with B which was 2 ish.作者: parott 时间: 2013-4-10 22:45
ahh yes the t-stat, i dont remember the exact question (maybe the t-stat of oil)
All i know, is none of my formulas worked.. thats actually the one where i picked 2.1作者: luda002 时间: 2013-4-10 22:45
I think I went with 2.1 but I could have put 4. I kept getting a number around 5-9 after working that formula 40 which ways from Sun. I spent waaaaay too much on that question, hell, too much time on the Quant sect for that matter.
What the question about using level of oils vs price change? Question asked what it would do to the model. I think I put down C which was something about bad statistical inference……and I think that was wrong.
Did anyone figure out the inflation knowing oil price the previous two months?作者: ftwcfa 时间: 2013-4-10 22:45
the oil/inflation one was just a plug and chug. the change in oil was -7 and then i took 4.85% from the chart they had- don’t remember the exact answer but it worked out fine to one of the answer choices.
t stat i didn’t know, took a guess. r i got wrong which is just upsetting, no negative sign for me. the conf interval i only did one std dev not 2. got -.43. what was the last one?
quant hurt- i thought i had done fine until i came back to AF. ouch.
