(a)
Construct a time series plot.
-A time series plot contains a series of 10 points connected by line segments. The horizontal axis is labeled Week and ranges from 0 to 10. The vertical axis is labeled Demand (in cases) and ranges from 0 to 30. The points are plotted at regular increments of 1 week starting at week 1 and ending at week 10 and appear to vary randomly between 15 and 25 on the vertical axis.

(b)Use a three-week moving average to develop a forecast (in cases) for week 11. (Round your answer to two decimal places.)
F11 = (???) cases
(c)Use exponential smoothing with a smoothing constant of ? = 0.4 to develop a forecast (in cases) for week 11. (Round your answer to two decimal places.)
F11 = (?????)cases
