<p>i did a paired because the individual woman and man aren’t symetric at all</p>
<p>@Soccer572 yes, but they took two separate samples of 10 men and 10 women which is why I concluded that it was a two sample t test.</p>
<p>I thought it was one sample of 8 models of cars.</p>
<p>It was a Matched Pairs t-test. There weren’t different samples of gender, thus there’s no need for a 2-sample test. It was matched pairs because it concerns the difference in the model, thus having the mean of difference as the correct way to go.</p>
<p>wait so that one was matched pairs?? Sooo did i get 0/4 for that one for doing two sample t-test</p>
<p>I heard from students that there were hardly any calculator questions on the multiple choice, mostly just on concepts. Is this true? I heard the first FR question was real easy and Question 6 was hard. Can anyone help me out on the free response questions and multiple choice? Thanks.</p>
<p>@procracumber I don’t think you will get 0 if you performed the two sample right I think you can get a 2</p>
<p>I had form O and for the women vs men car thing. I didn’t use any test. I just explained how the data does not evident an correlation… I’m screwed…</p>
<p>So is there a consensus on the residual plots for question 6?</p>
<p>What if I used a difference of proportion z-test on the cars I checked for normality. I am fine for half credit?</p>
<p>Also on 5 what was the method?</p>
