<p>Do you guys think that they would omit the histogram picture due to the typo? I myself didn’t even notice and was confused on how to relate the answer to the histogram.</p>
<p>What did you guys get for the question about: Rolling 3 fair 1-6 dice. X is the lowest of the number. Then choose you to choose the distribution of X.</p>
<p>I chose the graph with the distribution highest for 1 and continuing going down till 6.</p>
<p>Is it just me or was the p-value for the chi-squared .0615… ?</p>
<p>i got .011</p>
<p>@ephermeralbliss @___@ I know what you guys are talking about but it isn’t 12 times the weight of each of the eggs (aka the X value) since all the eggs have different weights. However we can assume that their standard deviation is the same because they’re from the same population. So in a carton, you have 12 sets of X and one set of an empty carton, thus its 12 times the variance NOT 12^2 times the variance.</p>
<p>and I don’t know what the heck was with the histogram LOL. and I got 0.011 for chi-squared like jackpot18</p>
<p>@Niceboat yep I got what you got for both of them.</p>
<p>@jackpot18 But wasn’t it just a 3x3 Matrix ? @_@ Oh my gosh what did I do</p>
<p>@ephemeralbliss o how i hate chi square, didnt do that problem at all TT_TT
@niceboat yes you were right
and awww dang it!!! i did the egg thing wrong cuz i did sq root of (standard deviation^2 - the other standard deviation^2/12
so you weren’t supposed to divide by 12?</p>
<p>@castor I think you’re right… I didn’t think enough about it. There goes more points</p>
<p>Niceboat same here, made the most sense. What was that top and mid level employees one and how the hell do you solve for it?</p>
<p>it was (.5<em>.4)/((.5</em>.4)+(.5*.1)=.8</p>
<p>i thought it was a 3X2 not 3X3?</p>
<p>I also got that for the top/low employer question. ^^. </p>
<p>For the question about mice did you guy choose matched pair with similar size mice?
I was stuck between that and match pair with randomly selected mice.</p>
<br>
<br>
<p>^Niceboat I put the matched pair with similar size since it had to do with what they were trying to test.</p>
<p>Woo that Top and Mid level one through me off, the wording on it felt atrocious. I saved it till the end, went back reread it. For whatever reason in my mind I really had to double that .4 ;)</p>
<p>@TheBombingRange
0.5 times 0.4 + 0.5 times i forgot the other number but i think 0.1
then you get that number is the prob a employee being …actually i forgot
but it was 0.25/divided by the number from above equation
if you tell me the answer choices i can remember and tell you</p>
<p>Same here. I thought it wouldn’t make sense to do a matched pair design without identical mice (since it says that the mice were of different size) but I picked it anyways.</p>
<p>its was definitley similar size</p>
<p>hey guys can anyone start a Tinychat we don’t want our scores canceled</p>
<p>@apkid3 That one was confusing to me as well.
I put the one where all 5 players had 20 games since it was an actual set number.</p>
<p>@apkid me too i guessed on 38!! even though i forgot the question i remember the number it was something about regression r ight?</p>
