Hello, we are give na table of data and I want to caculate the standard error:

How do you do that?

Note:

Here is the data:

Age of a car| repair cost in 1000's of $

_________________________________

X | Y

4 | 1

6 | 2

7 | 5

8 | 4

9 | 4

10 | 5

Note:

I have comouted the coree coeff, and have an equation for that. Just need to know how do I obtain the standard error from my table - what is the formula?

Thanks!
