Frank, i'm going to try to help you out with your baseball question.
00:03
And first of all, i can't tell by your numbers how they're oriented.
00:07
So i don't know which ones are the salaries, and i don't know which ones are attendance and where these decimals lie.
00:15
And this is, for instance, how the data shows to me.
00:18
It shows arizona diamondbacks, nationals, and then it shows this, and then a dot in numbers and another dot in more numbers.
00:27
So let's just describe what you need to do.
00:29
I have a ti -84, assuming you do as well.
00:34
And into your list one, you want the independent variable.
00:38
The attendance is to be the dependent variable.
00:42
And the total team salary needs to be your independent variable.
00:51
So you need to input those into list one and list two.
00:55
And then you can go to linreg of a plus bx on list one and list two, and you can get your regression equation.
01:08
And it will be some value that looks like this.
01:11
And it will give you more values for your display.
01:14
And then next, it asks, let's see.
01:20
Your first question says, i have to scroll way to the end of yours to be able to see it.
01:28
What is the expected attendance when the salary is $100 million? so you would want to substitute in place of the x variable that 100.
01:45
And that will give you, since the x value is the team salary, this would tell you what the attendance is, the expected attendance...
