So i entered this data into my calculator as a 3 by 3 matrix.
00:05
And i have a ti -84, and i'm going to assume you have something similar.
00:11
And so we want to find, first of all, we know that your question is, it says that the regions are independent versus dependent.
00:23
And we want to know what the expected value is for southeast republican.
00:29
So we want to go to southeast republican, and we would like to know what the expected value is for that.
00:36
So we need to take this row total times the column total divided by the table total.
00:44
And so when i look at the values, i find the row total is 102.
00:49
The column total is 94.
00:57
I have to switch back to another screen to see that question.
01:02
And the table total is 337.
01:07
And so that will give you that value.
01:10
And so 102 times 94 divided by 337 gives us a 28 .45.
01:20
And let's see what you need to round that to.
01:23
Looks like you want that, well, it doesn't specify...
