4. Professor Hong and his friend John and Sarah Connor are planning a recreational
outing and have constructed the following payoff table to help them decide which
activity to engage in. Assume that the payoffs represent their level of death and
dismemberment for each activity under the various possibilities for sentient cybernetic
organisms they may encounter. They have no idea which of the terminators, the T-X,
the T-1000, or the T-100, they might encounter on their outing.

(1) Use maximax, maximin, minimax regret, Hurwitz (alpha = 0.3), and equally likely
methods to come up with a vacation place for Professor Hong. Show all your work
and include your regret table.
(2) If the group is optimistic, what decision should they make?
(3) If the group is pessimistic, what decision will they make?
(4) If the group chooses to minimize their maximum regret, what activity will they
choose?
(5) If the group is neither optimistic or pessimistic, what decision will they make?

respectively, then what decision should be made using the expected value

respectively, then what is the EVPI for this situation?
