- See the answer A local movie studio wants to determine which of two new scripts they should select for their next major production. The manager feels that script #1 has a 70% chance of earning Php100 million over the long run, but a 30% chance of losing Php20 million. If this movie is successful, then a sequel could also be produced, with an 80% chance of earning Php50 million, but a 20% chance of losing Php10 million. On the other hand, she feels that script #2 has a 60 % chance of earning Php120 million, but a 40% chance of losing Php30 million. If successful, its sequel would have a 50% chance of earning $80 million and a 50% chance of losing Php40 million. As with the first script, if the original movie is a "flop," then no sequel would be produced. What is the expected payoff from selecting script #2?The management of Pearson Institute of Higher Education (PIHE) has decided to run a registrationpromotion to give students some discount on their fees.

- Students in Mr. Samir class are required to do a half hour team presentation on a topic of their choice. Mr.Samir randomly assigns students to teams. Students have approximately three weeks to research andprepare, including two hours of class time. Marks are given based on an instructor evaluation of thepresentation combined with a peer evaluation by their team members. Lina, Ali, Hanin and Majd wereassigned to Team. During their first team meeting they introduced themselves and began to decide on atopic. After 45 minutes, they were still trying to settle on a topic. They finally settled on MoneyManagement, however the instructor informed them that another team had already chosen that topic butConflict Management was still available. During the last 15 minutes of class time, Lina tried to convincethe group that they should present a role-play of conflict. Ali wanted to do research and give a more detailed,informational presentation.

The table below identifies the work elements, times, and immediate predecessors. Work Element Time (Sec.) Immediate Predecessor(s) A 25 - B 18 A C 20 A D 5 B, C E 12 C F 8 E G 16 D, F H 12 G Use one of the heuristic decision rules described in Table below to balance the assembly line so that it will produce 90 units per hour. Clearly state the decision rule you use and complete the below table using the selected rule. Decision Rule Logic Longest work element Picking the candidate with the longest time to complete is an effort to fit in the most difficult elements first, leaving the ones with short times to “fill out” the station. Shortest work element This rule is the opposite of the longest work element rule because it gives preference in workstation assignments to those work elements that are quicker. It can be tried…#6) A group of medical professionals is considering constructing a private clinic. If a patient demand for the clinic is high, the physicians could realize a net profit of $120,000. If the demand is low, they could lose $55,000. Of course, they do not have to proceed at all, in which case there is no cost. In the absence of any market data, the best the physicians can guess is that there is a 50-50 chance the demand would be high. a) Create a decision tree. b) What should the medical professionals do? What is the payoff? c) The physicians have been approached by a market research firm that offers to perform a study of the market at a fee of $5,000. The market researchers claim that their experience enables them to use Bayes’ theorem to make the following statements of probability: -probability of high demand given a positive survey result = 0.82 -probability of low demand given a positive survey result = 0.18 -probability of high demand given a negative survey result = 0.11…

The money can be placed in Treasury notes yielding an 8% return or in municipal bonds at an average rate of return of 9%. Bank regulations require diversification to the extent that a t least 50% of the investment be placed in Treasury notes. Because of defaults in such municipalities as California and Texas, it is decided that no more than 40% of the investment be placed in bonds. How much should Sears Investment invest in each security so as to maximize its return on investment?2. A real estate developer must decide on a plan for developing a certain piece of property. After careful consideration, the developer has two acceptable alternatives: residential proposal or commercial proposal. The main factor or state of nature that will influence the profitability of the development is whether or not a shopping center is built close by and the size of the shopping center. There is a 20% chance of no center being built, a 50% chance of a medium shopping center built, and a 30% chance of a large shopping center. If the developer selects the residential proposal and no center is built, he has a further set of options: do nothing $400,000 payoff; build a small shopping center himself $700,000 payoff; or put in a park resulting in $800,000 payoff. Should a medium shopping center be built nearby, his payoff for residential would be $1,600,000 and large shopping center results in a $1,200,000 payoff. If the developer selects the commercial proposal and no center is…
