Question

pass attempts data. For pass attempts and yard gained are as follows
Pass attempts x 116 90 82 108 92
Yards gained y 1001 823 851 873 839

Find y if x=95
please help

Answer 1

I found the average ratio of pass attempts to yards gained to be 1:9.07. So, with that I got 862 (rounded up) yards gained for 95 pass attempts. Hope it's helpful.

Answer 2

Thank you SO much. I had come up with: 867 utilizing the TI-83. I have attached my work - perhaps we can find where the error of descrepancy is between the two answers?

Answer 3

I don't have an answer. The points don't lie on a straight line so you need some kind of model, a way to fit a line or a curve to the data. Have you studied anything like that?

Answer 4

What did you tell your calculator to do? (I don't run Word so I can't read your file).

Answer 5

We have learned about line regression, yes.
. I entered in all of the values for Attempts x into L1, and the y -values into L2 on the TI-83.
To enter values in a list: Press STAT, then 1-for edit, and enter. Move cursor down until all x- values are entered into L1, and then use the left arrow to move over to L2 to enter in the y-values.

Answer 6

Well, then you have an answer! The formula is a bit complicated, if you are really interested it's explained here
http://en.wikipedia.org/wiki/Simple_linear_regression
but I think you can probably just move on with that answer.

Answer 7

Whew! Thank you. I was hoping that plugged in the correct outputs from the TI-83 into what was needed for the next step(s).

Answer 8

I appreciate all of your help! Have a great day!
