Assume that the current date is February 1, 2003. The linear regression model was
applied to a monthly time series based on the last 24 months' sales (from January
2000 through December 2002). The following partial computer output summarizes the
results.

For the same set of observations on a specified dependent variable two different
independent variables were used to develop two separate simple linear regression
models. A portion of the results is presented below.
Model 1:
r^2= 0.92
s= 165
Model 2:
r^2= 0.85
