At the beginning of each week, a machine is in one of four conditions: 1 = excellent; 2 = good; 3 = average; 4 = bad. The weekly revenue earned by a machine in state 1, 2, 3, or 4 is 100, 90, 50, or 10, respectively. After observing the condition of the machine at the beginning of the week, the company has the option, for a cost of 200, of instantaneously replacing the machine with an excellent machine. The quality of the machine deteriorates over time, as shown in the file P10 41.xlsx. Four maintenance policies are under consideration: Policy 1: Never replace a machine. Policy 2: Immediately replace a bad machine. Policy 3: Immediately replace a bad or average machine. Policy 4: Immediately replace a bad, average, or good machine. Simulate each of these policies for 50 weeks (using at least 250 iterations each) to determine the policy that maximizes expected weekly profit. Assume that the machine at the beginning of week 1 is excellent.

Deborah Kellogg buys Breathalyzer test sets for the Denver Police Department. The quality of the test sets from her two suppliers is indicated in the following table: percent defective probability for winter park probability for technology dayton enterprise 1% 0.65 0.25 3% 0.25 0.25 5% 0.10 0.50 For example the probability of getting a batch of tests that are 1% defective from Winter park technology is 0.65. Because Kellogg orders 10,000 tests per order, this would mean there is a 0.65 probability of getting 100 defective tests out of the 10,000 tests if Winter park technology is used to fill the order. A defectice breathalyzer test can be repaired for $0.50. Although the quality of the…
Jon is preparing a newsletter to his clients. As part of his newsletter, he reports their economic outlook for the coming year. He samples 85 of his clients, and they report that they expect to hire 7.8 new employees during the coming year. Last year all of his clients averaged 6.3 hires with a standard deviation of 4.0. Jon wants to know if the expected number of new hires has significantly increased at the 5% significance level. What are the null and alternate hypotheses?
In 1996, McDonald’s (MD) launched Campaign 55, reducing the prices ofits “flagship” sandwiches with the objective of regaining market share. Beforethe launch, suppose MD’s management envisioned two possible outcomes: astrong customer response or a weak response. Industry experts were notvery optimistic about the campaign. They assessed the probability of a strong response to be .40. MD predicted an expected profit of $50 million if theresponse proved to be strong. If the immediate customer response was weak,management believed that all was not lost. If MD could persuade themajority of its franchisees to back and help fund the campaign, the resultingprofit would be $20 million. However, if the majority rose up against thecampaign, the red ink would fly, and McDonald’s profit would be -$100million. MD considered these two outcomes to be equally likely.a. Given these assessments, construct a decision tree to determine MD’sexpected-profit-maximizing course of action.b. Suppose that MD has…
The Nitro Fertilizer Company is developing a newfertilizer. If Nitro markets the product and it is successful,the company will earn a $50,000 profit; if it is unsuccessful,the company will lose $35,000. In the past, similar productshave been successful 60% of the time. At a cost of $5,000,the effectiveness of the new fertilizer can be tested. If thetest result is favorable, there is an 80% chance that thefertilizer will be successful. If the test result is unfavorable,there is only a 30% chance that the fertilizer will besuccessful. There is a 60% chance of a favorable test resultand a 40% chance of an unfavorable test result. DetermineNitro’s optimal strategy. Also find EVSI and EVPI.
Letz Products has two decisions to make, with the second decision dependent on the outcome of the first. The company intends to build a new plant. Letz has the option of conducting its own marketing research survey for which the results will either be positive or negative. The information from this survey could help it decide whether to build a large plant, to build a small plant, or not to build at all. Letz recognizes that although such a survey will not provide it with perfect information, it may be extremely helpful. Using figure 1 – explain to your client (Letz) what the above decision tree shows. You are required to show all working.
According to Runzheimer International, a typical business traveler spends an average of $281 per day in Chicago. This cost includes hotel, meals, car rental, and incidentals. A survey of 70 randomly selected business travelers who have been to Chicago on business recently is taken. For the population mean of $281 per day, what is the probability of getting a sample average of more than $266 per day if the population standard deviation is $47?

When performing sales mix analysis , which one of the following is false : a. Producing and selling more units of the product with a higher contribution margin would likely decrease the breakeven point b. Making changes to the sales mix will likely cause a change in the breakeven point c. The sales mix is usually assumed to be remain the same . d. Shifting the sales mix to the product with a lower contribution margin will likely ncrease the overall contribution margin e. Normally the calculation of the breakeven point for multiproduct is more complicated than that for a single product
Mr. A wants to study the salient factors that may influence the adoption of Social Networking Sites (SNS) for educational purposes. For this, he identifies the variables such as trust (TR), emotional attachment (EA), resource and material sharing (RA), communication (COM), and collaboration (COL) that may affect the adoption of the Social Networking Sites (SNS). Confirmatory Factor Analysis (CFA) was employed to perform reliability and validity checks, and Structural Equation Modelling (SEM) was employed to test the proposed conceptual model. This study could help instructors and managements at higher educational institutions to formulate strategies to encourage the students to use social networking sites for academic purposes. Based on the above information, answer the following questions. Develop the conceptual model of the study. Develop the alternative hypothesis of the study. Develop the research objective of the study. Suggest the target…
Cost Estimation; High-Low and Regression Methods The Mac Davis Company specializesin the purchase, renovation, and resale of older homes. Mac employs several carpenters and paintersto do the work for him. It is essential for him to have accurate cost estimates so he can determinetotal renovation costs before he purchases a piece of property. If estimated renovation costs plus thepurchase price of a house are higher than the house’s estimated resale value, it is not a worthwhileinvestment.Mac has been using the home’s interior square feet for his exterior paint cost estimations. Recentlyhe decided to include the number of external openings—the total number of doors and windows ina house—as a cost driver. Their cost is significant because they require time-consuming preparatorywork and careful brushwork. The rest of the house usually is painted either by rollers or spray guns,which are relatively efficient ways to apply paint to a large area. Mac has kept careful records of theseexterior…
