3. A coefficient of determination r2 =15.6398 indicates which of the following must be true?

Solution

Coefficent of determination r^2 tells that how much variability in dependent variable is accounted for by the independnet variable. r^2 must be between 0 and 1 (inclusive).

It is also reported as percentage. In that case it must be between 0 and 100%.

I am assuming that you provide percentage of r-sqaure. That is r-sqaure is r2 =15.6398 %. It indicates that 15.6398% variability in dependent variable is accounted for by the independnet variable.
