4. What is the difference between trend and seasonality in time series data?
5. Here are the errors associated with a particular forecast over the past 5 months, in
chronological order: 5, 10, -15, 0, 8. In which month was the forecast perfectly
accurate? In which month was the forecast the least accurate? In which month or
months was the forecast too high? (Noteshaper Ramp Up # 23)
6. Tutoring Center needs to allocate tutors this week for office appointments, so it needs

Monthly data for the sales of certain product at a local company during the las 9 periods are shown in below table. (Fill all the blanks. Allow 2 decimal values).
a. Determine the forecasts for periods 5 through 9 using three-period moving averages, and the forecasts for periods 7 and 9 using six-month period moving averages.
b.Calculate the forecast errors for three-period moving averages and forecast errors for six-period moving averages.
c. Calculate the MAD for three-period moving averages and six-period moving averages.
d. If a smoothing constant of 0.4 was analyzed for the data, and you were informed that forecast for period 1 was 1,450; based on these assumptions, calculate the forecast for period 2.
