The simple random sample is
A.	2779.
B.	2798.
C.	Alysha, Emily, Devon, and Natalie.
D.	Alysha, Emily twice, and Devon.

I'm guessing C, though I'm not sure...  It couldn't be A or B imo, but D shouldn't be anyone twice....

Which of the following statements is true?
A.	If we used another list of random digits to select the sample, we should get four different students.
B.	If we used another list of random digits to select the sample, we would get at least one student with an odd number.
C.	If we used another list of random digits to select the sample, the result obtained with the list actually used would be just as likely to be selected as any other set of three names.
D.	If we used another list of random digits to select the sample, we would get two students with odd numbers and two students with even numbers.

I also say C because each choice is likely to be choosen.

C is correct for #1. Since you can't pick the same person twice, you skip over the duplicate number - same if you encountered a 0, you'd just skip it as if it wasn't there.

And C for #2 seems to be the only one that makes sense, though "as any other set of three names." is weird because I thought it was supposed to be a sample of four.

the result obtained with the list actually used would be just as likely to be selected as any other set of three names.

konradzuse · Answer

I think it means the result plus any other 3...

both look correct, maybe it's just a typo?

I hate stats sooooo much. :)

anonymous · Answer

That's what I'm guessing. None of the other choices make sense, and I think it's about how random is random, so results are equally likely.

yeah!
