a) Interpret the slope and intercept of the regression model.

b) Interpret in this context.

c) If the Center had a goal of achieving an average tracking error of 65 nautical miles by 2015, will they make it?
Explain.

d) Use technology to compute the Durbin-Watson statistic and comment.

e) What cautions would you state about your conclusion?
