0:00
All right.
00:01
So in this case, we have a degrees of freedom of 20 with our kai squared.
00:05
And we are looking for the probability that the kai squared value is less than or equal to 24.
00:12
So a few ways of doing that.
00:14
You can use your, you can use your calculator.
00:23
We have a kai squared cdf.
00:26
My lower limit is zero because that's the lowest kai square can go, 24.
00:33
So kye squared cdf from 0 to 24 with 20 degrees of freedom.
00:39
It's my lower, my upper, there's my degrees of freedom.
00:44
And that gives us 0 .7576.
00:52
And so a, we're going to find the probability kx squared is greater than k is equal to point 10.
01:01
So we know that the tail probability...
