Boston-Chicago Q-class demand has std. deviation σ = 5.3. Compare allowable decrease and increase for this constraint with 1.28σ (10% critical value for the normal distribution). Does the allowable increase for the demand constraints exceed the 1.28σ? How about the allowable decrease? If the threshold of 1.28σ is not exceeded, there is at least 10% chance that the shadow price for the constraint may be inappropriate
