For a particular maximization problem, the payoff for the best decision alternative is $$16\mathrm{.}7$ million while the payoff for one of the other alternatives is $$12\mathrm{.}9$ million. The regret associated with the alternate decision would be

$$29\mathrm{.}6$ million

$$16\mathrm{.}7$ million

$$0\mathrm{.}129$ million

$$3\mathrm{.}8$ million
