A tourist center is open on weekends (Friday, Saturday, and Sunday). The owner-manager hopes to improve the scheduling of part-time employees by determining seasonal relatives for each of these days. Data on recent traffic at the center have been tabulated and are shown in the following table:
a. Develop seasonal relatives for the shop using the centered moving average method.
b. Develop seasonal relatives for the shop using the SA method.
c. Explain why the results of the two methods correlate the way they do.
