<p>Number 6 was about APUSH
Number 5 was about
Number 4 was about
Nber 3 was about carpet
Number 2 was about parties
Number 1 was about athletes
Is this right you guys? What were 5 and 4 about? I’m trying to figure out how I did but I basically forgot the questions as soon as I stepped outside of the testing room :(</p>
<p>@ Dream no4 was cholestrol and no5 was wind mills</p>
<p>5 was about wind and power or something like that, and 4 was about a cholesterol drug</p>
<p>If you were to write a regression equation and show the variables say on an energy related problem would it be enough to substitute y hat with the variable?</p>
<p>@DreamChaser2013: Well they could attempt to find out your identity based upon all of your posts and info that you provided when signing up for an account. Granted, you may have posted no revealing info and your email and everything else may be false, but there is always the possibility that they do find out. It’s just a question of how much you’re willing to risk the possibility of getting your score cancelled. </p>
<p>Anyways, Stat was pretty easy. MC was easy and that #6 was one of the easiest that I’ve ever done. And regarding a certain question that was discussed, just remember the rules about what changes when a value is added/subtracted from a set of data vs. when the set is multiplied by a constant.</p>
<p>i personally thought that was an easy MC test, predicting 35+/40. Frq’s were easy, #1 was probably the wierdiest. #2 was easy, except maybe for c. #3, 4, and 5 were straightforward easy and 6a was easy, 6b and c required some though, hope i got those, but i didn’t get 6d at all. I think i got a 5 caz u don’t need to much to get a 5 in stats. But sometimes those frq graders get nit picky with wording.</p>
<p>Haha, did anybody actually read that history question? I didn’t.</p>
<p>would the markers take marks off for messy work…
cuz for number two, i realized i made a mistake 3minutes before the test ended, so
i had to scratch everything out for number two with a pen then did chi square in like 3 mins. lol
that was epicc<br>
and also last part of the question2, i made a mistake with graphs, so i had to change it that too… </p>
<p>btw did u guys get same graphs for male and female?</p>
<p>I don’t think on number 2 you had to do chi square. To test if the data were independent I think you had to find out if the probability of A and B equaled the probability of A times the probability of B, which it didn’t using the data from the table. The graph should have been the same frequencies for both the males and females.</p>
<p>ya the mc was easier than usual</p>
<p>So in general-not necessarily within context of any question-would you rather be a fast runner or a strong weightlifter as an athlete? Doesn’t it technically depend on the sport?</p>
<p>I think I’d rather be a faster runner ;)</p>
<p>I’d prefer being stronger. After all, the ladies love the strong men ;)</p>
<p>I’d prefer to be about 5 lbs weaker but like 10 secs faster…not to be specific or anything</p>
<p>I thought the FRQ were really easy, and i had extra time so i spent it checkin my work, then i asked the grader why they would only choose 8 apartments rather than 9 so they could get one from every floor…hahaha</p>
<p>Meh, it was more fun analyzing the APUSH question, writing about how only a few knew the answer - was writing “gee, if only a few actually knew this, America is in for some rough times when I grow up” going to annoy my grader? (edited out actual percents)</p>
<p>(I boxed it, put an x through it and said don’t grade)</p>
<p>For FRQ1a, was it not Normal? For part b, do you interpret it like “the player is ___ standard deviations above the mean?” and for part c, did you find the z scores of both speed and strength for each player, find the probability of them both, then multiply them together?</p>
<p>For FRQ2b, I said they were not independent because I did test for independence: P(AandB)=P(A)P(B), P(A|B)=P(A), and P(B|A)=P(B). Is that right?</p>
<p>I got that they weren’t equal, which should make sense since party preference should not depend on gender.</p>
<p>For part c of the SD question, player B’s stats were higher z-score wise than player A’s, so he was the player that the teams should have chosen.</p>
<p>^No, only his strength z score was higher, and not by much. Player A’s speed z-score was much better so Player A was the correct answer. </p>
<p>I think :)</p>
