***OFFICIAL AP Statistics Thread 2014-2015***

Is this right for the last question: (only interested bout the method questions)
a.
b. Method 1
c.Method 2
d.
e.Method 1
f.Method 1

Definitely method 1 for the last 2, i can’t seem to remember what the rest of the questions were asking though.

uhh b. was the histogram and c. was which method would be less variability or something :slight_smile:

The histogram one was Method 1, And I think method 2 for part C because it was asking which one had less variability for one day, so method 2 would be better

@AnniiT: Basically for # part b it said the proportion IS 0.02. But I put it CAN BE, but the CI does not provide CONVINCING evidence that the proportion is EXACTLY 0.02

I mean 0.2. And 0.2 is just slightly less than 0.21, and we are not sure the true p is 0.2.

For multiple choice 1, 2 were they both C?

so glad This is over :)))

And for that multiple choice question with the interval, and asked about sample proportion… do you do the interval addition divided by 2?

@Jasondinh1 I thought it was convincing evidence lol… hopefully I didn’t lose too many points in the FRQ section.

I think i did a lot better than i though on #6

@AnniiT :I had to reread that question many times and I realized that the problem was in the way the question was worded. I pretty sure that it said p is 0.2. But we cannot conclude p is 0.2, we just know p can be in that interval

@Jasondinh1 For 2 or 3 parts of that question, I put the same response; that since the confidence interval contained the given value, the proportion was possible. How about the other parts? Did you write the same thing I said?

@Anniit: The first part of that question I put yes because 0.2 is in the interval. the second part I wrote the same as I said in the previous posts. The third one I got ME= 0.03, and got a new CI. For the last part I said p is not in the CI, thus the conclusion is wrong

Do we had to show any work for margin of error…coz it was basically common sense.

Did anyone have form M? I don’t think any of my questions match up with the ones discussed already…My #6 on the FRQ was about gorillas and availability of food and toughness of food?

Ooooo I feel bad for you man…this means you a totally diff form

@AnniiT: And the way you answer that question " the proportion was possible" is totally different from "the proportion is (0.2) " like the question said

Ummmm… Did anyone else who had Form O think that test was insanely easy? I want to say I got a 5 for sure, but I’m scared that it was so easy that I messed up everywhere… It was much easier than our final exam, which was a past AP exam, and I barely got a 5 on that, so I’m hoping I just made a 5. I was very pleased with the MC and most of the FRQs… I definitely made at least a 2 on every FRQ.
And I’m not trying to sound cocky either. Normally I never feel good about any test no matter how well I do, but I just feel so good about this one… Sorry if I come off that way!

@PhilipL I got Form O and yes, it was so easy! I feel like I definitely got a 5. Hopefully my FRQs are good.
