Yes, you have all the info you need.  Hint:  first you have to find a
regression equation, and all the info to do that is on your output.

Oh yeah - forgot that - here it is:

Y = ?0 + ?1x +e

But, I'm not sure I'm reading the table right. 

Is it:
110,000 = 11.4621 + -2.3725 + 3.3513  (am I suppose to use the
Constant STd Error figure?)

or have I messed that up completely?
