<p>i definitely spaced my time pretty well and finished with about 5 minutes left.</p>
<p>i wrote all these funny notes to my readers during the test. i'll write what they were tomorrow or sunday when i'm less tired.</p>
<p>something crazy though -- one part said "if you needed more room take up this space below."</p>
<p>that question literally took me about 20 second to do and i <em>easily</em> fit it in the space provided.</p>
<p>haha same here</p>
<p>yea, i just did the problem in the space provided, and wrote an explanation of what i did in the extra space. but for the actual calculations, i felt the space provided was sufficient.</p>
<p>Anyone know when the questions will be posted on CB?</p>
<p>r we allowed to talk about the answers yet?</p>
<p>I think we can tlak aobut the free response now. It's been over 48 hours</p>
<p>yeah, i think its ok to discuss the free reponse. cb has posted the questions up, see for yourself...</p>
<p>so very easy, I think I got a 5</p>
<p>so since were allowed to discuss... what was the answer to the median question? (#2 subset c) i think that was a wording bias :D i mean i just stopped and stared at that it since i had no idea what to do. in the end i wrote 2 but was it 1? i remember it was right skewed, but thats all i knew</p>
<p>im pretty sure the answer was 1. ahh i think i screwed myself over on a lot of the other free response though i dont know what i was thinking</p>
<p>which test did you take: form a or b?</p>
<p>i have a question for the median thing... i got the right answer, but i dont know if i will lose points for my method of getting the right answer ?
Since it gave you p(x) i found the fraction each number occured, and reduced it to x/20. Then i put those numbers into my grapher, and found the median. Is that okay if i said i did it that way? or were they expecting us to do it another way?</p>
<p>also, 1 B is no right? my friend is trying to tell me that the answer is yes.. but that makes no sense</p>
<p>I went with the median = 1 for that question because, if i remember correctly, the cumulative proportion of 0 was .35 and the cum. prop. of 1 was over .5, so that means .5 must be greater than 0 and (I figured) located at 1.</p>
<p>It's definately no. They only selected 1 rural and 1 urban area to take data from which really, you need samples from more areas. [makes face] I don't exactly remember how I explained it.</p>
<p>thats what i told her... okay, glad im not going crazy lol</p>
<p>what did u guys say was the bias ? i was saying that many people w.o diplomas were homeless, may not have phones, etc?</p>
<p>Yup, but ouch, homeless? Lol. I just said there's a greater probability that they won't have phones and the true proportion will be understated.</p>
<p>For the bias, I said they would potentially be ashamed to answer that they hadn't received a diploma.</p>
