<p>Does any one have the AP Statistics Practice Exam from College Board?</p>

22

<p>The test is this Friday, y’all! Get excited! (or cry yourself to sleep like I’m doing, but hey, either way).</p>

23

<p>2 MORE days till I can rock the ap stats test and hopefully get a 5!! I’ve been getting low to mid 5’s on old practice exams. By friday though, I’ll be crazy psyched for the exam</p>

24

<p>Anybody have any tips for programs on calculator?
I’m self-studying for this. </p>

25

<p>@Hawkace assuming you have a graphing calculator, you should be familiar with using the built-in CDF/PDF functions, plotting regressions, and running z- and t-tests, and interpreting their results. Other than that, you won’t really need any additional “programs.”</p>

26

<p>Can someone clarify the different “versions” of dealing with standard deviation in different situations? It’s kind of confusing me.</p>

27

<p>Here are some notes I took during my class’ final review. We went over stuff kind of fast so if there are any mistakes or anything to add feel free to comment on the doc. (Anyone has permissions to comment)

28

<p>do we have to show our work on frq or can we just use our calculator?</p>

29

<p>@zah0813‌ Show work that you did on the calculator by writing out everything that you did on the calculator. </p>

30

<p>Can we compile I list of multiple choice anwsers?</p>

31

<p>I had form g</p>

32

<p>Easiest test ever. So glad that I self-studied Stats. </p>

33

<p>Hawkace, did u have form g? Do u remember any mc anwsers</p>

34

<p>Free response was hella easy. MC had a few diffucult ones though.</p>

35

<p>So no one remembers mc</p>

36

<p>For the Q with the car models was it a 2-sample or a one sample T test?</p>

37

<p>what did people do for the hypothesis test? Matched pair?</p>

38

<p>@superstarlala‌ it was a two-sample t test for the difference of population means. It kind of gave that one to you when it told you that they wanted the difference (women - men). </p>

<p>@Soccer572‌ what are you talking about? Like what were the hypotheses for the car problem?</p>

<p>Overall it seemed a lot easier than I was expecting. I’m feeling a strong 4 if not a 5 depending on how I did on the MC (I took a nap the period before and was completely out of it).</p>

39

<p>@austere i thought it would be a matched pair because they were talking about the same car model</p>

40

<p>i got form O and if this is for the men vs women car problem, i did a two sample t test</p>
