Data collected on the yearly registrations for a Six Sigma seminar at the Quality College are shown in the following table:

a$)$ Calculate the forecasted registrations for years $2$ through $12$ using exponential smoothing, with a smoothing constant $()$ of

$0\mathrm{.}35$ and a starting forecast of $5\mathrm{.}00$ for year $1($round your responses to one decimal place$)$:

b$)$ Mean absolute deviation based on the forecast developed using the exponential smoothing method $($with a smoothing

constant $()=0\mathrm{.}35$ and a starting forecast of $F_1=5\mathrm{.}00)$ is

registrations $($round your response to one decimal place$).$
