We have been given a p -value picture and we want to correctly label it.
00:09
So we have this curve, which could be a normal curve or it could be a t -distribution.
00:15
And we have a here and b here.
00:20
So you've already labeled the p -value area.
00:24
So whatever area this is, is the p -value.
00:27
Based on that, what is a and what is b? we'll start with b.
00:31
B, you can see, is in the middle of this curve.
00:33
This is the mean of the curve.
00:37
So b is the mean, mu.
00:39
Specifically, it is mu zero.
00:44
So what does mu zero mean? well, it's the mean based on the null hypothesis.
00:50
The null hypothesis, h zero, is that the population mean is mu zero...
