1. ## Confused about t-stats and P-value

Can anyone explain to me how to get a P-value for a t-stat of 3.573 with 9 degrees of freedom. The tables are confusing to me- I'm taking an online class, so I'm trying to teach myself. Any help would be greatly appreciated.

2. most tables are organized witht the df expressed running across the top and the t values on the side. To find your p value just first find the df and the works down that colum until you reach the row with your coresponding t. Generally if your t value falls in between two in the list you take the average, I think been a long time since I had to use tables.

3. In Excel, use the function =TDIST(x,deg_freedom,tails)

substitute 3.573 for x, 9 for deg_freedom, and 1 or 2 for tails

4. ## Thanks for the help

Thank you both for your help. I am going to try the excel trick right now.

I don't seem to have that function on my excel - is there another name for it possibly? Or can I do it on my TI 83 Plus?
Thanks
