c. What is the probability that demand for this book will be within 20 percent of the mean forecast (i.e., between 160 and 240 )? Use Table 13.4. Note: Round your answer to 4 decimal places. d. What order quantity maximizes Dan's expected profit? Use Table 13.4. e. If Dan orders the quantity needed to achieve a 95 percent in-stock probability, what is the probability that some customer won't be able to purchase a copy of the book? Note: Round your answer to 2 decimal places. f. Suppose Dan orders 300 copies of the book. What is Dan's expected leftover inventory? Use Table 13.4. Note: Round to the nearest whole number. g. Suppose Dan orders 300 coples of the book. What are Dan's expected sales? Use Table 13.4. Note: Round to the nearest whole number. h. Suppose Dan orders 300 copies of the book. What is Dan's expected profit? Use Table 13.4. Note: Round to the nearest whole number. Dan McClure owns a thrlving independent bookstore in artsy New Hope, Pennsylvania. He must decide how many coples to order of a new book, Power and Self-Destruction, an expose on a famous politiclan's lurid affairs. Interest in the book will be intense at first and then fizzle quickly as attention turns to other celebrities. The book's retall price is $20, and the wholesale price is $12. The publisher will buy back the retailer's loftover copies at a full refund, but McClure Books incurs $4 in shipping and handling costs for each book returned to the publisher. Dan believes his demand forecast can be represented by a normal distribution with a mean of 200 and a standard deviation of 80 . Table 13.4 is the standard normal table. Note: If a part of the question specifies whether to use Table 13.4, or to use Excel, then credit for a correct answer will depend on using the specified method. a. Dan will consider this book to be a blockbuster for him if it sells more than 400 units. What is the probability that Power and SelfDestruction will be a blockbuster? Use Table 13,4. Note: Round your answer to 4 decimal places. b. Dan considers a book a "dog" if it sells less than 50 percent of his mean forecast. What is the probability this expose is a "dog"? Use Excel. Note: Round your answer to 4 decimal places. i. How many books should Dan order if he wants to achieve a 95 percent in-stock probability? Use Table 13.4
