Ive been posting many questions, hopefully the alst for awhile:

You have collected data on sales and population within a one mile radius on 12 stores of a supermarket. You determined that the adjusted coefficient of determination is 93.85%. Determine the coefficient of determination.


I think there isn't enough info, but I guess I could be missing something

I am going to assume "coefficient of determination" is the R2 coefficient. See http://www.csus.edu/indiv/j/jensena/mgmt105/adjustr2.htm [Broken]. You have to determine what your n (number of observations) and k (number of Independent Variables) are. The problem you posted does not give you these.

n = 12 (number of stores)

k = 1---> one independent variable, one dependent (I can asume single regression)

also, its [tex]r^2[/tex] because its a sample
