Here i have to find the expected values in equation a.
00:05
Each expected value is a line total times column total divided by the grand total of 10 ,000, 450.
00:27
And here i need to use excel to find the observed failures.
00:40
Let's do this.
00:42
So let's start from, yeah, let's show the first column, which is smoking level.
00:52
And there are four smoking levels, 1 to 10, 11, 20, 21, 30, and 30 plus.
01:02
And the first group is african -americans.
01:10
Now let's write down the expected values.
01:37
Next one is native hawaiians, then latino, then japanese -americans.
02:32
And then next one it whites.
03:14
Okay, this is done...
