Hi everybody,

First thank you for your time, I really appreciate that.

The funny thing is that i wrote the questions in the way that they look like homework but is wasn't my purpose. My homework is to learn SAS Base, so this is my explanation:

I got the data from an Excel sheet, import it to SAS, clean in and made scatter plot matrix, some graphs and the simple reg model which is

UK_Sessions = 202,2 + 0,34 * Spain_Sessions

Well, form my own I have the question "Are the two parameters estimated significantly different from 0? and why?"

My professor said that we only need to know the SAS code and the reg model but it would be great to know about the residual (this is for the 10 out of 10 I think

) so I thought a good way to talk about the residual is if we can know if this is a good model only by seeing the residuals.

If you think this is only for homework and I don't want to work in it you are free to think it but I think this is over the homework, it's like studying more than the professor want me to do.

I will give you some SAS code and the work I've got until now.
