With $=0\mathrm{.}3$ and the initial forecast for January of $$1\mathrm{.}90,$ using exponential smoothing, the forecast is: $($Round your responses to two

decimal places.$)$

With $=0\mathrm{.}5$ and the initial forecast for January of $$1\mathrm{.}90,$ using exponential smoothing, the forecast is: $($Round your responses to two

decimal places.$)$

Based on all of the months in the forecast, the mean absolute deviation using exponential smoothing where $=0\mathrm{.}1$ and the initial

forecast for January of $$1\mathrm{.}90$ is $$,.($Round your response to three decimal places.$)$

Based on all of the months in the forecast, the mean absolute deviation using exponential smoothing where $=0\mathrm{.}3$ and the initial

Based on the mean absolute deviation, the better forecast is achieved using $=$ Dell uses the CR$5$ chip in some of its laptop computers. The prices for the chip during the past $12$ months were as follows.
