The above Table shows the number of visitors per quarter recorded at one of the tourist parks in the United States. Using the Excel and multiplicative technique to decompose seasonal data:

a) Calculate the 4-year moving average

b) Calculate the centered moving average (CMA)

c) Isolate seasonal factors or indexes; and, where necessary, normalize (scale) the factors

d) Using the factors above, deseasonalize the original time series data

e) Run the regression analysis for deseasonalized data and Period t. Take Period t as independent variable and deseasonalized time series data as dependent variable

f) From the output generated in e) above, write the regression equation
