(a) Find the coefficient of determination and interpret the result.

?

(Round to three decimal places asneeded.)

How can the coefficient of determination beinterpreted?

A.

The coefficient of determination is the fraction of the variation in money spent that is unexplained and is due to other factors or sampling error. The remaining fraction of the variation is explained by the variation in money raised.

B.

The coefficient of determination is the fraction of the variation in money spent that can be explained by the variation in money raised. The remaining fraction of the variation is unexplained and is due to other factors or to sampling error.

(b) Find the standard error of estimate se and interpret the result.

?

(Round to three decimal places asneeded.)
