Please respond to the weekly forum $2$ provided in Week $2.$

Forecast demands using weighted moving average. Please apply weights of $0\mathrm{.}3$ for the most

recent period, then $0\mathrm{.}4,$ then $0\mathrm{.}3$

Given the following data:

Prepare a forecast using smoothing constant $=0\mathrm{.}40.$

a$)$ Subjective estimate $($for this example, use $60).$

b$)$ First actual value $($na$$ve approach$).$

Given the following data:

c$)$ What are the exponential smoothing forecasts for periods $2-5$ using $=0\mathrm{.}7?$

d$)$ Use na$$ve approach for $1^{st}$ week
