Consider the following time series data.Week 1 2 3 4 5 6Value 18 13 16 11 17 14a. Construct a time series plot. What type of pattern exists in the data?b. Develop the three-week moving average forecasts for this time series. Compute MSEand a forecast for week 7.c. Use a  .2 to compute the exponential smoothing forecasts for the time series. ComputeMSE and a forecast for week 7.d. Compare the three-week moving average approach with the exponential smoothingapproach using a  .2. Which appears to provide more accurate forecasts based onMSE? Explain.e. Use a smoothing constant of a  .4 to compute the exponential smoothing forecasts.Does a smoothing constant of .2 or .4 appear to provide more accurate forecasts basedon MSE? Explain.
