As you read through a general report that contained the multiple regression model, you have noticed that the adjusted R-squared that has been reported is greater than the regular R-squared. Discuss the likelyhood of this occurence.

I didn't want to confuse you with my "answers" but here is my thoughts for the question...
The adjusted R-squared takes into consideration the number of independent variables while the regular R-squared does not. When new independent variables are added to the model, the adj R-value will increase if the t-stat on the coefficient estimater of the new variable is greater than absolute 1.
Am I on the right track?

I don't think I could have answered this even in 1960!! But I'm still a fairly good speller, and it should be "likelihood" and "occurrence"!!! Sorry. Love to be helpful if I could.

You could also go to mathworld.wolfram.com and type :"multiple regression" in the search box -- it comes up with some information.

It looks to me like you've just copy and pasted all three of the statistics questions that you've posted here. I'll help you learn but I don't want to do your homework.
