a. Construct a time-series graph and comment.
b. Calculate a three point moving average and place this on your time-series graph.
c. Interpreting each shift as a season, determine the seasonal components using a multiplicative model.
d. Use your results in (b) and (c) to predict the output for the three shifts in day four
