Answer A, B, C, D please. I don't need other people's answers about environmental forces affecting the pharmaceutical industry which is totally irrelevant to my question..

If you just copy and paste irrelevant answers, you'll get thumbs down.

2.4 Supply Risk Management Consider a pharmaceutical company facing random demand DU(0,10] (continuous uniform) for the flu vaccine during the flu season. There are two suppliers. Supplier 1 has a unit ordering cost C; = $1M and a random yield factor Xi ~ U[0.5, 0.8) (continuous uniform); that is, if the firm orders Q unit from supplier 1, he only receives Si = X1 Q and pays c Si. Supplier 2 has a unit purchasing cost c2 = $2M and is completely reliable (yield factor X2 = 1). The firm needs to place the order before the flu season; during the flu season, each unit fulfilled demand brings revenue $4M. Suppose the company order Q from supplier 1 before the flu season; during the season in case of supply shortage(i.e., received supply from supplier 1 is less than realized demand), the company will meet all the shortfall (the amount of demand that cannot be met by the stock delivered by supplier 1) by expediting or rushing orders from supplier 2 (at unit purchasing cost c2 = $2M). The percentage of the total demand fulfilled by supplier 2 is called rush probability R. Assume sample size N = 3 x 103. a) Suppose the order quantity Q = 20. What is the expectation and 95% confidence interval of profit W? What is the expectation of the rush probability R? b) The possible order quantities are Q {1, 2, ...,20}. Compute the expectation of rush probability R(Q), the expectation and 95% CI of the profit W(Q) under each order quantity. Plot the mean and CI of W(Q) and find the optimal order quantity Q*. c) Can you explain why dual sourcing strategy, i.e., using both suppliers (0
