<p>What did everyone think? </p>
<p>I thought it was pretty easy... I definitely over studied. Were there even any Chi-Squared questions?</p>
<p>Yea there was a FRQ on chi-square</p>
<p>For the last question, not to break the rules, but were you supposed to set the probability in terms of k = to .28 to find k?</p>
<p>k was equal to .04 if it was properly inserted into the tree diagram. I got it wrong, did a very complicated thing haha.</p>
<p>i made note to emphasize that i knew the critical value and the standard error so hopefully my lack of knowing k will only be minus 1.</p>
<p>the mc were pretty average, 4 questions that I was unsure of, but nothing that required an abnormal application of principles.</p>
<p>I think I got a 5, but wouldnt be horribly disappointed with a 4</p>
<p>there was no numeric value for k.</p>
<p>Yeah guys no specifics.</p>
<p>I found it so much easier than practice tests I’ve taken, definitely a pleasant surprise. I only need a 3, but I’m pretty confident I got a 4.</p>
<p>I also got .04 for k on last problem.
.28 = k + (1-k).25
k = .04</p>
<p>cpu scientist, i also thought k would be a theoretical value, but everyone said you had to solve for it.</p>
<p>i thought it wasnt too bad, the free response was easier than i thought it would be. i didnt under stand part c on #2 where you had to fill in the proportions for the town</p>
<p>That was easier than I was expecting. The FRQs were a bit tricky, but I don’t think I missed anything other than 2b. I’m also sure I screwed up my assumptions and conditions in many ways.</p>
<p>i meant part 6c 
sorry</p>
<p>for d you had to find it… which i ran out of time to do :(</p>
<p>A few of the FRQs were a joke, as usual. There were some pretty interesting ones as well; I thought the application demonstrated in problem 6 was cool.</p>
<p>Me too^ ughhh. I could’ve had a perfect on #6…</p>
<p>mhm i see…so did the tree have both theoretical and real numbers?</p>
<p>Well I guess my class didn’t prepare me well for reading computer spreads. It was pretty standard. I don’t really know how I did though.</p>
<p>Ugh I solved for k wrong even though I had the right formula. Do you think I’d get a partially correct on that? Or incorrect?</p>
<p>yes @ collegebound. for c you should have gotten</p>
<p>k + (.25-.25k)</p>
<p>or </p>
<p>k + [.25(1-k)]</p>
<p>Are you talking about 5 tito? I didn’t know how to either lol…</p>
<p>Was there a chi squared test?!?!?!</p>
<p>Same on number five. My teacher forgot to teach us that. 5A I had no idea; I think I figured out the other three parts enough to get some partial credit.</p>
<p>No, there was no FRQ chi-squared test.</p>
<p>at least i got something on 6 right. haha thanks cpu. did anyone else blank out at first at the sheer simplicity of #1?</p>
