<p>@mia “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>I did the square root of 40 thing, and just left my answer as that. however, some of my friends multiplied the mean and SD by 40…was that for part A or B??? im confused</p>
<p>and for the q thing i forgot to multiply by 5 because i was in a hurry. ■■■, any chance of partial credit??? or will the whole part be counted wrong? i showed the substitution w/ 5 in it but never actually did it on my calculator. i hate my life</p>
<p>the s.d was 1.1/sqrt(40) as for the testing , i tested the average # of min per song rather than as a whole, multiplying by 40 should have given you the same thing (the 40’s cancel out anyway…)</p>
<p>Damn, you guys must all have taken a different test, my FRQ #6 wasn’t about fish T_____T
Did anyone here take the other version of the test, where the last FRQ was about house prices and residuals??</p>
<p>Okay, I’m assuming the embargo has been lifted for this test. Can we like make a consolidated answers list like they do for every other one of these? Not like: 1) A, 2)B…etc, because nobody remembers. But if you guys can remember the answers you put down (for the multiple choice I mean) then we can figure it out.</p>
<p>I didn’t take the class or the exam but a girl in my AP Comp class was telling us how unprepared she was for it…
Apparently she answered exactly 9 questions, pulled out her Snuggie and took a nap the rest of the time.</p>
<p>I took Stat and Comp Sci, but luckily was overprepared for Comp Sci, so was able to devote more energy to Stat, which I was slight less prepared than ideal.</p>
<p>I’m pretty sure I got a 4, but would definitely like a 5. I didn’t not answer any MC, but I probably got several wrong. FRQs were easier, but I got caught up on one that I misread and it sucked up 20 minutes (and I probably got it wrong). For that question I wish I was less tired, but overall it wasn’t too bad.</p>
<p>@charizarrd, FRQ #5 was about fish, 6 was about storms.</p>
<p>I think I did well on all of them except maybe 2 and 4.</p>
<p>“You can’t ever talk about multiple choice unless you want your scores cancelled…”</p>
<p>omg, this does NOT actually happen, people. get a life.</p>
<p>MC question:i don’t remember exactly, but it was pretty early on & asked for the ho & ha of the given situation. so each choice was pretty long. my question is, is the ho ALWAYS ‘=’. i hope not. i think i answered 'ho>something & ha</=something, cause that’s what the situation made it sound like :/</p>
<p>'“You can’t ever talk about multiple choice unless you want your scores cancelled…”</p>
<p>“omg, this does NOT actually happen, people. get a life.”'</p>
<p>If you had read these boards, you would know that it does happen…but whatever, it’s not like I care if you do or do not get in trouble, just giving everyone fair warning.</p>
<p>Since we CAN discuss FRQ’s as they are posted online by CollegeBoard for everyone to read, let’s post correct answers. In a format like
QUESTION 1
A
B
C
QUESTION 2
A
B</p>
<p>H0 is always “=”. It is the null hypothesis and therefore it assumes that the parameter is equal to a value. For the Ha it is >, <, or <>(not equal to), since this one hypothesizes that the parameter is either below, higher, or different from that value.</p>
<p>This is one of the (many) things that the AP Statistics test oversimplifies.</p>
<p>Some statisticians insist that the null hypothesis must always be a single point. Some say that it frequently makes more sense to allow it to be a range. And on everything covered in the AP curriculum, the two approaches lead to the same calculations and same answer.</p>
