<p>Yes, could someone pm me 9 and 34 as well?</p>
<p>why is everyone asking for 9 and 34? i don’t remember any questions being flawed, i thought they were all alright, except for a few confusingly-worded ones of which there were still correct answers</p>
<p>what was 34??? pm</p>
<p>are we allowed to exchange questions with others who took the exam privately??</p>
<h1>9 definitely had an answer. The answer was just in a different form lol. Tricky CollegeBoard. Don’t know about #34 though.</h1>
<p>And I think you can, smarts1 (even though you’re not really suppose to)…</p>
<p>i def got answers for those two…</p>
<p>can someone pm me 9+34?</p>
<p>i think i got an answer for 34 but pretty sure i left 9 blank</p>
<p>If someone could pm me 9 and 34 thatd be great. thanks.</p>
<p>I used the wrong test for one of the questions, but had all the conditions and writing good for it. Is it completely wrong or can I get partial credit? I realized this about 20 minutes after the test and have hated myself for a while.</p>
<p>which one are you talking about?</p>
<p>erasmuss22…i think i might have done the same thing as you !!!</p>
<p>yeah… i think i did a z-test when i should have done a t-test for one of the FRQs. I have no idea how many points they’d take off, but my guess is not too many, especially if you show work. Because the p-values you get are pretty similar, it’s just one small mistake. It won’t bring you down from a 5 to a 4 or a 4 to a 3 or anything.</p>
<p>I misread a question and I thought we were suppose to give the CI for each fire station…-_______-" so I wrote 2 CIs, when it was just suppose to be one. This in turn screwed up my answer in the next part.</p>
<p>T-test? I don’t remember doing a t test since sigmas were known…</p>
<p>In general, T tests are used when we don’t know the population’s standard deviation.</p>
<p>Sigma(pop’s std. dev) is different from the sample’s std dev.</p>
<p>But they gave us both sample standard deviations. o.O</p>
<p>which is why t-test should be used. when sigma is not known but the sample’s std dev. is known.</p>
<p>lol. Are you freaking serious. ■■■</p>
<p>that’s my take on it. anyone else?</p>
