Consider the following time series data.

Week	1	2	3	4	5	6
Value	19	11	16	10	18	14

Develop the three-week moving average forecasts for this time series. (Round your answers to two decimal places.)

Week	Time Series Value	Forecast
1	19
2	11
3	16
4	10
5	18
6	14

Compute MSE. (Round your answer to two decimal places.)

MSE =

What is the forecast for week 7?

(c)Use = 0.2 to compute the exponential smoothing forecasts for the time series.
