Foreign fish production. Overfishing and pollution of U.S. coastal waters have resulted in an increased dependence by the United States on the fishing grounds of other coun- tries. The table below describes the annual fish catch (in thousands of metric tons) in all fishing areas of Peru and Chile for the years 2000 to 2008.

Compute an exponentially smoothed series for both Chile and Peru, using a smoothing coefficient of w= .5. b. Plot both actual series and both smoothed series on the same graph. Describe the differences in variation of catches over time between the two countries. For exam- ple, do they move up and down together over time?
