<p>thnxanother mistake</p>
<p>for number 1 on the free response, was it appropriate for a linear model lot of my friends said no because they drew scatterplots, and it was exponential</p>
<p>I’m not going to discuss yet on the off chance that CB actually would go to all that trouble. However, I would like to comment that I finished all the FR but was unsure about one of them until the very end where I had a realization and fixed it. Looking for a 4 or 5.</p>
<p>also, i was referring to the car problem in the free response</p>
<p>for the FR did u guys talk bout block design?</p>
<p>10 character</p>
<p>OK i think i did well on this</p>
<p>No, but that question’s answer was “increasing sample size for one sample and keeping other same would decrease variation”</p>
<p>“estimator” question was another one.</p>
<p>not that doesnt make sense, trust me. i asked my teacher after the test</p>
<p>How doesn’t it make sense?</p>
<p>Violate CB rules at your own risk…the embargo hasn’t been lifted yet…</p>
<p>Not discussing anything, but the FR section was complete bogus.</p>
<p>block design or stratified?</p>
<p>Generally:
60-100: 5
49-59 - 4</p>
<p>that’s from the 2007 released exam. I think the curve might drop a bit this year</p>
<p>Could you link me to that grading scale? 60, not a 70 is minimum for a 5?</p>
<p>my teacher said 69/70 was a 5</p>
<p>i discussed stratified for one of them.</p>
<p>also, for #1, i said that is was a good fit because i drew the residual plot & it looked random. plus, the r^2 value was pretty high, so…</p>
<p>Did anybody else say there wasn’t significance for a question (calculator stats were given, I just looked at r value, .36ish)</p>
<p>whatt
I got a pretty curved resid plot
and just by looking at it, it was pretty curved</p>
<p>umm it was apparently not a best fit from what i hear, because the scatterplot for clearly exponential and thus linear pattern wouldnt be it or the residual plot did show some pattern so… yeah</p>
