Tee shirts
Tee Shirts Unlimited is providing shirts for an upcoming sports tournament.They assume demand will be either 2000,3000,4000,or 5000 shirts and they need to decide whether to produce 2000,3000,4000,or 5000 shirts.The payoff for each production/demand combination is shown in the table below.
$$\begin{array} { | c | c | c | c | c | } \hline \text { PAYOFFE } & & \text { Demand } & & \\\hline \text { Altematives } & \mathbf { 2 0 0 0 } & \mathbf { 3 0 0 0 } & \mathbf { 4 0 0 0 } & \mathbf { 5 0 0 0 } \\\hline \mathbf { 2 0 0 0 } & \$ 10,000 & \$ 10,000 & \$ 10,000 & \$ 10,000 \\\hline \mathbf { 3 0 0 0 } & \$ \mathbf { 3 , 0 0 0 } & \$ 15,000 & \$ 15,000 & \$ 15,000 \\\hline \mathbf { 4 0 0 0 } & - \$ 4,000 & \$ \mathbf { 8 , 0 0 0 } & \$ 20,000 & \$ 20,000 \\\hline \mathbf { 5 0 0 0 } & - \$ 11,000 & \$ 1,000 & \$ 13,000 & \$ 25,000 \\\hline\end{array}$$
-The probabilities for demand levels 2000,3000,4000,and 5000 have been estimated to be 20%,40%,15%,and 25% respectively.Which is the expected value of perfect information?
