All right, so here we are looking at the p value.
00:04
So what happens is you put in the middle of your sampling distribution, you assume that your given mean or population proportion is true.
00:20
So then the average of all of your sample mean should be equal to that, or the average of all of your, or the average of all of our, or the average of all of our, sample proportions should be equal to that.
00:34
So we assume it's true.
00:36
We put that in the middle of our curve.
00:37
And then what we do is we take our sample mean and put it, let's say right here, x bar or p hat.
00:46
We put that and then we shade either one or two tell, depending on what our alternate hypothesis is.
00:51
Our p value is the area to right, left, or both of our sample mean or proportion given that the null mean our proportion is true...
