Forecasting rain jacket demand months in advance is tricky. ‘ Yak & That ’ ?has only been operating for three years, with varying sales success. Based on past sales, current market conditions, and expert judgment, 1 2 ‘ Yak & That ’ ?employees have independently estimated demand for the new rain jacket design this upcoming season. Their estimates are presented in Table 4 . ?To assist in the decision on the number of units for the production run, management has gathered the data in Table 5 . Table 4 : Estimated Demands ? Table 5 : Monetary Values Variable production cost per unit ( C ) : £ 8 0 Selling price per unit ( S ) : £ 1 0 0 Salvage value per unit ( V ) : £ 3 0 Fixed production cost ( F ) : £ 1 0 0 , 0 0 0 1 4 , 0 0 0 1 6 , 0 0 0 1 3 , 0 0 0 8 0 0 0 1 4 , 0 0 0 5 0 0 0 1 4 , 0 0 0 1 1 , 0 0 0 1 5 , 5 0 0 8 0 0 0 1 0 , 5 0 0 1 5 , 0 0 0 7 Note that S is the price ‘ Yak & That ’ ?charges retailers.

What mean and standard deviation should ‘ Yak & That ’ ?use for the demand distribution? [ 3 ] b . ?Use a spreadsheet model to simulate 1 0 0 0 ?possible outcomes for demand in the coming year. Based on these scenarios, what is the expected profit if ‘ Yak & That ’ ? produces Q = 7 8 0 0 ?rain jackets? What is the expected profit if ‘ Yak & That ’ ?produces Q = 1 2 , 0 0 0 ?rain jackets? What is the standard deviation of profit in these two cases? [ 6 ] c . ?Based on the same 1 0 0 0 ?scenarios, how many rain jackets should ‘ Yak & That ’ ?produce to maximize expected profit? Call this quantity Q . [ 3 ] d . ?Should Q equal mean demand or not? Explain. [ 2 ] e . ?Create a histogram of profit at the production level Q . ?Create a histogram of profit when the production level Q equals mean demand. What is the probability of a loss greater than £ 1 0 0 , 0 0 0 ?in each case?
