True

True or False, Constant demand is a key assumption of the EOQ model.

True

True or False, For questions with payoff measured in profit, EVwPI is always greater than or equal to EVwoPI.

True

True or False, Regret is the difference between the payoff associated with a particular decision alternative and the payoff associated with the decision that would yield the most desirable payoff for a given state of nature.
