Consider a finite population with five elements labeled a, b, c, d, and e.
00:05
Ten possible simple random samples of size two can be selected.
00:08
So first thing you want us to do is list the ten samples.
00:12
So we could have a, b, a, c, a, d, a, e.
00:19
Then we could have b, c, b, d, b, e, c, d, c, e, and d, e.
00:28
So there's the ten.
00:29
For part b, using a simple random sample, what is the probability that each sample of size two is selected? so the probability of being selected is one out of ten, or you could say 0 .10.
00:47
And then for c, assume a random number corresponds to a, two corresponds to b, and so on.
00:53
So let's go ahead and do that...
