Statistics 2010

<p>I think I may have done that wrong bc I jus looked at the pvale</p>

<p>I wasn’t sure, I could make a conclusion based on p-values, but that wouldn’t be the same conclusion I would draw when looking at the r value?</p>

<p>Also, the question about two guys making 90% confidence intervals was really weird. Didn’t know if a higher proportion of people sampled was better.</p>

<p>i hate ap statistics test makers</p>

<p>LOL, saywhatz, why did you post the exact same post four or five times…?</p>

<p>Nobody answered?</p>

<p>& they’re not going to…</p>

<p>…because the repeated posts were super annoying.</p>

<p>@ Kablam, totally agree:)</p>

<p>^^hahaha, precisely :)</p>

<p>did no one like my significance test about the ETS? i thought it was funny</p>

<p>How did you do a for #6?</p>

<p>@trav23, I looked back to find it. I enjoyed it. -highfive-</p>

<p>to the person/people who found the stats curve online, can yous link me up? :)</p>

<p>i used a 2sampt test for the mean one where it was like
ho: M1=M2
ha: M1<M2</p>

<p>forgot what it had to do with though
it was the last of the frq’s before the investigative task</p>

<p>i thought this test was pretty hard… </p>

<p>for the frq, number 2, what did you guys put? the one about the music radio thingy… i didn’t know how to solve that at all. sampling distribution of mean something something…</p>

<p>i knew it was simple but i couldn’t get it in my head for some reason i was like OH SNAP, its number 2 and i don’t even know how to freaking do it!</p>

<p>ohh is that the one that asked us to “discuss the mean distribution”?
i thought they had already done that in the question haha i just copied the question :frowning:
and the second one you find the zscore of 4.1-3.9/1.1 and then normalcdf the (zscore,99) to find the prob</p>

<p>…so am i the only one that thought 4 was the hardest thing ever invented? I think I did well on all the FRQ’s aside from that and 6(because i ran out of time)</p>

<p>What was the formula we were supposed to use?</p>

<p>^which one was 4?</p>

<p>4 was the one about the car.</p>

<p>grrr today… so many freakin distractions and delays. aargh i’m just super glad to get that out of the way</p>
