No need to answer everything! Just plot the actual visitors and the forecasts. Compare the accuracy of the forecasts in the 1985 to 1990 period with those subsequent to that period.

Cynthia’s Design Studios had sales in the last four months of $12,700, $14,500, $19,100, and $15,800. Sales are related to how many designers Cynthia has on duty. The sales forecast helps her decide on the proper staffing levels. What is the forecast for the fifth month using a two-period moving average? What is the forecast for the fifth month using = 0.8 in an exponential smoothing model with A4 = $15,800 and F4 = $17,913 to get things started.
