So basically you'll be setting up your hypotheses, and you can have your hypotheses be that the one proportion is equal to the other, or that they are not equal.
00:11
And that would mean that their difference is zero.
00:14
Or we can have this be that this is greater than or equal to that proportion, and this could be less than that that proportion.
00:25
And that would be that if we take the difference, the difference we would assume is zero here.
00:30
And here we would assume if we did p1 minus p2, that it's a negative.
00:34
And likewise, you can have this.
00:36
It all depends on what your hypotheses are from the way the question is worded.
00:43
And then you'll be calculating, and you'll do your checks, to make sure that your assumptions from number one, question one, are followed...
