Consider an airline single-leg capacity allocation problem with 4 classes. The demand is assumed to be normally distributed with the following demand data:

a. Calculate the protection levels using EMSR-a

b. Calculate the protection levels using EMSR-b

c. The optimal protection levels for this problem is known to be = 16.7, = 42.5, = 72.3. Compare the expected revenue from using the optimal protection level, the EMSR-a levels, and the EMSR-b levels. Assume the total capacity is C=90.
