<p>The test is matched-pair t test because the cars are of the same model. Also, they even give you the differences which is a huge hint. I got graph III for 6d.</p>
<p>I did a matched-pair test, too, and put graph III (forget which one that was - pretty sure it was engine size though?).</p>
<p>yes, mizo. in general, a scattered residual plot means the association of x and y is more linear. </p>
<p>@mizo I said it was the wheel length not the engine size because the residual plot should be randomized in order to be helpful for getting more accurate results. @soccer57 I said it was just a one sample t (using the differences provided) and thats what most of our class thought too. @Hawkace the answer is (2/5)^3 obviously. There are only 2 days that are acceptable and 5 days in a week and there are 3 weeks. So for week one there is a (2/5) probability and for week two (2/5) and for week 3 (2/5). So you multiply them all up.</p>
<p>do you think 30/40 MC and say 70% FRQ might be a 5?</p>
<p>look up your score on <a href=“AP Statistics Test Score Calculator - AP Pass”>http://appass.com/calculators/statistics</a></p>
<p>I’m thinking that I got a 25/40 on MC followed by 3-4-3-4-3-2. That comes out to a 71 which should be a 5. @testing97, I think that is a 5.</p>
<p>Can we get a google doc going? Also, the minimum significance level one was .97 right? </p>
<p>@Decimation I guessed that, hopefully its right! Was there a .003?</p>

<p>@topnotchnerd101 That is not a reliable source. 63% is definitely not a 5. I think I got around a 25/40 on MC and 3-4-3-4-3-2 on FRQ so that is a 71%.</p>
<p>@Decimation why do you think the answer for the minimum significance level was 97%. i believe it was 95%</p>
<p>Barrons prepared me well… the test seemed quite easy.</p>
<p>The pvalue was .028 and it was a two tailed test. The null hypothesis would be the difference = 0 so in order for the confidence interval to include 0, you would have to fail to reject, and thus .03 would be the significance level, making the answer .97.</p>
<p>@topnotchnerd101 no, it said 3 days from 3 weeks not a day per week. Sorry, but you’re wrong. I already went over it with like 5 people.</p>
<p>wait so we cant talk about the test right? </p>
<p>@decimation i think there was a similar problems on pratice tests</p>
<p>What method did you guys choose for the free response question about the class of 1988 income. You could have either chosen method 1 or method 2… Do u think it was one of those questions where you could have chosen either and still have gotten full credit if you argued your point?</p>
<p>PM me for my explanations id rather not risk it</p>
