<p>I would say that test was easier than last year’s EnviroSci, but still loses to last year’s US Gov for easiest AP test ever.</p>
<p>i thought the frq was pretty easy compared to the mc…</p>
<p>here’s a website that will let you play around with what scores you think you got to find out what your AP score will be: [AP</a> Pass - AP Statistics Calculator](<a href=“http://appass.com/calculators/statistics]AP”>AP Statistics Test Score Calculator - AP Pass)</p>
<p>Sorry if this has been asked already, but does anyone remember the question about the pink candies? It’s like each box is supposed to have 50%, if 50 are tested and the expected value is off by 7? or 8? then the machine is shut down. Something about the probability of the machine shutting down?</p>
<p>I’m not sure if it’s Form B or not… D:</p>
<p>for the fish one i got m1 is less than m2…DID I MESS UP? ;O</p>
<p>^It depends on what your mu’s were</p>
<p>Yes I got .399 for the p value of the fish one too! I accepted the null, because it’s not significant at the .05 level. And for the #6 one I had no idea how to accept or reject it, i think i ended up saying there was a significant difference, although I can’t remember at all…</p>
<p>I don’t remember any of the MC, but did any one else get nervous that question 6 seemed too easy?</p>
<p>um, no. i see it as a blessing from wherever.</p>
<p>yes, LET’S try to remember some MC questions. gah, CC was so helpful with that last year when i took ap biology. too bad i can’t remember anything from yesterday, lol : P</p>
<p>To Trav23: i hope you didn’t say you ACCEPTED the null hypothesis. Theyll take points off for that. You can never accept a null hypothesis, instead you have to say there is no evidence to prove it wrong</p>
<p>for the fish one, i got q=6.4, too, for whoever asked. #6 wasn’t that hard, just part e.</p>
<p>for #1, i drew a line graph - i don’t know what compelled me to - and then i said that 1/sqrt of x would be a better fit because i couldn’t remember the word EXPONENTIAL.</p>
<p>for whoever put up a z score - 3.9-4.1/1.1 - isn’t it supposed to be divided by 1.1 over the sqrt of 40 (because it was a sample of 40??)</p>
<p>CAR SUCKED. I got the first part but not the second and/or third if there was one.</p>
<p>Anyone here who thought MC was harder than FR? I left 3 blank and pray that I only got 7 wrong. It just frustrates me that although I’m quite sure I know my statistics, I did not think the AP test was a piece of cake like others have stated. I really hope I passed. D:</p>
<p>For the candy one, you use geometric distrib right?</p>
<p>i never used geometric distribution…
there has never ever been a geometric distribution on an ap exam before
but if “ap exams are independent of each other” who knows… haha</p>
<p>for number 6 on the frq did anyone use the median as an average?</p>
<p>how ****ed were you guys that there werent more binomial questions on this test? im pretty sure none on the mc. they’re such easy points.</p>
<p>dudes please answer my question…im seriously freaking out about it…</p>
<p>for number 6 on the frq did anyone use the median as an average</p>
<p>NO, i used the mean. and it clearly stated the average, so u were to use the mean, and calclate the Q, which i believe was 6.4!</p>
<p>^ditto.</p>
<p>“how ****ed were you guys that there werent more binomial questions on this test? im pretty sure none on the mc. they’re such easy points.”</p>
<p>SAME. they couldn’t have asked one binomial question? dayumm, lol.</p>
<p>for the s.d of the car distribution I used the formula that the variance is equal to the difference between the count and expected value squared times the probability, then i took the square root to get the s.d</p>
<p>and got a high p value for the next part which for # of owners of e being less than 12, meaning that it’s pretty likely to get less than 12 owners, the next part kind of assured me when it asked how to sample so i at least get 12 of d and e…</p>
