Consider the decision tree shown below which is for deciding on whether we should do a project. Use the backward method, and calculate the EV (round your answer to the nearest integer). The cost of sample information (X) in Dollars is 126. Positive values imply revenue and negative values imply cost. Try to maximize profit. Withdraw $ 500 Success 0.25 0.75 Do the project Failure $-100 No sample info, Withdraw -$X $ 500 - X Success 0.10 0.90 Getting sample information at the cost of $X Do the project Failure $-100-X Bad 0.45 results S-X Withdraw $ 500-X Q.55 Success Good 0.80 results Do the project 0.20 Failure S-100-X
