<p>ugh, stupid car question. i got the first part of part a, but not the second part of part a. which left me completely useless in solving part b :[</p>
<p>for number 2 on the frq…were you suppposed to multiply the mean and std. deviation of the population by 40?</p>
<p>is the car question about the car models?.. that one was nasty.</p>
<p>What graphs did everyone draw on the FRQ? I think I drew a triple bar graph for the hurricane one and a bar graph for the starlings (although I feel like I should have drawn a RESID plot now…).</p>
<p>does anyone remember what the celsius problem was asking for?</p>
<p>I wouldn’t discuss any specifics about MC, but the ones people seem to be continuously asking about seem to be common sense.</p>
<p>“I think I drew a triple bar graph for the hurricane one”</p>
<p>omg, i did that. but i feel like it’s totally not a real thing. as i was doing it, i was sort of just like, ‘heh, i don’t know how else to set this up…’. it was basically three bar graphs separated by two lines drawn on the x-axis :/</p>
<p>^lol, if everyone is continuously asking about them, maybe they’re not so common-sensical? take your arrogance elsewhere, thanks <3</p>
<p>I don’t think you can’t compare distributions with bar graphs. I did histograms…</p>
<p>But for a histogram you need to have you x-axis evenly spaced out so it was impossible to do with the given data.</p>
<p>hey for the question about the fish hypothesis testing, did you get a really high p-value…like 0.399 or something like that? because I did
Ho: mu 1 = mu 2
Ha: mu1 is greater than mu 2</p>
<p>^yeahh, i think i got exactly that :]</p>
<p>Well, now that I feel like everything I did ontue FRQ is doubtful… did you all get something like 6.2 for the Q statistic?</p>
<p>when do scores come out?</p>
<p>Yep, and it was on the table. It corresponded to a p-value of .039 I think</p>
<p>Wow, sounds like I got some things right :)</p>
<p>I’m pretty sure it was a little over .40, ~.408</p>
<p>Was 28% an answer?</p>
<p>i got 6.2 for the q score</p>
<p>does anyone else felt rushed on time?? i barely finished. Do you guys think it was a hard exam overall or an easy one?</p>
<p>Good to hear, exoveerotch. Out of curiosity, wha did you say on the last part about interpreting the Q score? I think I said that the hurricanes were significantly different (reject).</p>
<p>I felt rushed, but I didn’t think it was too difficult overall. I did some erasing, but I think I got most of the points. Question 6 was much easier than anticipated.</p>
