<p>Not confirmed yet, but could be.</p>
<p>**** that test i hated taht ****.......free response blew but mc wasn't that bad.....on number 3 i forgot to do 1-p value.....u think that they will still give me some points because i got everything rite on that</p>
<p>3 on FR or MC?</p>
<p>3 on FR quizquick</p>
<p>oh yeah, but if you didn't do 1-p, wouldn't that be totally wrong?</p>
<p>are we allowed to talk about this even? if not moderator delete my post cuz i dont want my score to be cancelled lol</p>
<p>i dont know quizquick alot of my friend said i mite get a 1 or 2 because i had the right thinking (demonstrated some statistical knowledge)</p>
<p>i think S was the variance because that is the symbol they used in my book.</p>
<p>oh yeah, well moderators delete my thread(s) too :D</p>
<p>FOR EVERYONE WHO IS WORRIED ABOUT #6:
Keep in mind the test will be curved, and if that material wasn't on the AP curriculum, then it will be curved in all of our favor. If none of us got it, most likely nor did most of the world. No one here has yet said "Oh, six was easy!"</p>
<p>I too had no idea what S was... i was waiting for it to ask about R^2 at which point I would have nailed it, but meh. Number four was pretty dumb too, I didn't really get that one. I thought the MC was pretty easy, FRQ #1,2,3, and 5 were not terrible, and 4 and 6 werent fun.</p>
<p>Well, to say the least, on six I made up as much as humanly possible and bombed it anyway.</p>
<p>Oh, and the reason they gave so many lines for the interval question is because you actually had to write quite a bit: all the conditions, all the formulas, computing the formulas, identifying the variables you are using (xbar 1 and xbar 2, s, and n), and it didnt say to, but I wrote what the interval means....</p>
<p>6 was pretty easy; they gave you the formula and everything!? (Maybe I'm missing something big here, as I haven't taken the course [I read all of Barron's prep {and did most of the exercises} the night before taking the test])</p>
<p>Free Response was insanely hard. :(</p>
<p>I BSed my way through number 6, but two of the parts (c and d) asked for...the same thing? Which was confusing.</p>
<p>The one with the regression line, however.......no idea. My teacher is a moron. A quote from my stat teacher in class yesterday when we were going over old FRQs: "Hmm, I don't know what SE is." And then we get a free response on it. Thanks.</p>
<p>SE is standard error; isn't S just Sb (formula on formula sheet)?</p>
<p>Whatever, I need to go take a Calc BC practice test now :V</p>
<p>I was glad I did the MC first; otherwise my moral would have been sooooooooo low</p>
<p>octalcode- that's what I assumed S was...
b= S/SE</p>
<p>HAHA still couldn't answer the question though! I just said it was the variance. I [still] don't know.</p>
<p>It's the exact same thing and you know that. Who cares, so you can write the error function, big deal. Good job... You're just gonna look arrogant.</p>
<p>Oh, I guess I'll be the first.
6 was a cinch!
I did some plug and chug and drew some lines.
It's not F tests, and I'm 99% confident that it's a chi-square problem.
The hardest for me was the regression interpretation.
However, for the others I didn't write out everything (like variables, formulas) but I sorta made clear what I was doing. If they deduct a lot for it, oh well.</p>
<p>PRETTY SURE #6 FR KICKED MY BUTT. I never learned any of that. i had no idea what it was asking and pretty much guessed if i didn't put anything. i don't even think i got 1 point on number 6 which sucks since it's doubled. but after the test everyone at my testing place said that #6 sucked so hopefully everyone else does too so the curve is different.haha</p>
<p>isn't that weird formula for 6 just the chi-square value? i solved for the standard deviation and used that for the s. might not be right but that was the only thing i could come up with.</p>
