Consider the following time series data.

Year	Value
1	234
2	287
3	255
4	310
5	298
6	250
7	302
8	267
9	225
10	336

a. Use= 0.2 to compute the exponential smoothing values for the time series. Compute MSE and a forecast for year 11. b. Use trial and error to find a value of the exponential smoothing coefficient (rounded to 2 decimal places)that results in a smaller MSE than what you calculated for= 0.2. c. Compute the forecast for year 11 using the smoothing coefficientselected using trial error.
