A marketing research profossor is conducting a telephone survey and needs to contact at least 160 wives, 140 husbands, 110 single adult males, and 120 single adult females. It costs $2 to make a daytime call and $4 (because of higher labor costs) to make an evening call. The table shown below lists the expected results. For example, 10% of all daytime calls are answered by a single male, and 15% of all evening calls are answered by a single female. Because of a limited staff, at most half of all phone calls can be evening calls. Daytime Evening Percentages 25% Wife 25% 30% Husband 15% 25% Single male 10% Single female 15% 15% None 35% 5% What is the objective function of this linear programming problem?

This is all one question:   The following set of questions were developed to administer to the customers of a food catering business. Put yourself in the position of a customer who has ordered food from this catering business at least one time in the past. You have just received this survey in an e‐mail from the catering company. The e‐mail contains a link that takes you to a Web‐based survey process (such as Google Forms or SurveyMonkey). As you read each question, evaluate it carefully. Is it easy to answer? Do understand how to answer? Is there any confusion in your mind about what response is expected? Do you think your answer will be meaningful and useful to the system development team?   What is your company's name? On a scale from 1 to 10, how easy do you find the ordering process? 0‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐10   How long does it take to place a catering request?

Two methods are used to predict how many customers will call in for help in the next four days. The first method predicts the numbers of callers to be 23, 5, 14, and 20 for the four respective days. The second method predicts 20, 13, 14, and 20 for the four respective days. The actual numbers of callers turn out to be 23, 10, 15, and 19. Which method has the smaller mean absolute error (MAE)? Multiple Choice The first method The second method Cannot be determined Both methods have the same MAE

Consider the following case as you respond to the questions:HSO Corp. designs, manufactures and sells golf carts, scooters and similar vehicles. When a prospective client contacts one of their seven corporate offices, the office manager fills out an "intake questionnaire" to determine if HSO can meet the prospective client's needs. The office manager assembles a team of employees with expertise in design, production, marketing and accounting; the team reviews the intake questionnaire and determines if HSO can take on the order. If so, the office manager prepares a three-page written proposal for the prospective client; the proposal explains the responsibilities of both HSO and the client, along with a timeline and a budget. The proposal is forwarded to the prospective client electronically, and the client has ten calendar days to accept it. If HSO cannot take on the order, the prospective client receives an automatically generated form letter; if the prospective client does not accept…

Miles Filtration, Inc. provides maintenance services for water filtration systems throughout Southern Florida. Customers contact Johnson with requests for maintenance service on their water filtration systems. To estimate service time and the service cost, Johnson’s managers want to predict the repair time necessary for each maintenance request. Hence, repair time in hours is the dependent variable. Repair time is believed to be related to three factors: the number of months since the last maintenance service, the type of repair problem (mechanical or electrical), and the repairperson who performs the repair (Donna Newton or Bob Jones). Data for a sample of 10 service calls are reported in the following table: Develop the multiple regression equation to predict repair time, given the number of months since the last maintenance service, the repairperson, and the type of repair. What are the interpretations of the estimated regression parameters? What does the coefficient of…

A manager intends to order a new machine and must now decide on the number of spare parts to order along with the machine. The parts cost $496 each and have no salvage value. The manager has compiled the frequency distribution for the probable usage of spare parts:7 spare parts with frequency 0.05;8 spare parts with frequency 0.23;9 spare parts with frequency 0.08;10 spare parts with frequency 0.07; and 11 spare parts with frequency 0.57. For what range of shortage costs would stocking 9 spare parts constitute an optimal decision ? a. Between 231.5and 334.8 b. Between 192.9and 279 c. Between 289.3and 418.5 d. Between 96.44and 139.5

No Pain Corp Omar Amman, the CEO of No Pain Corp (NPC), is under stress. They produce transcutaneus electrical nerve simulation units (TENS) for pain control. Amman faces a new opportunity and is not sure how to go about it. Recently, the the Department of Health of Canada has approved low current TENS devices to be sold directly to consumers without a doctor’s note. This will come into effect in three months. In the past, one needed a doctor’s note and could rent the device from some companies. These TENS machines, as they are called in Canada, are popular, since the older population has found them to be effective in pain control with almost no side effects. Amman can sell the device via drug-stores and pharmacies as well as on Amazon. But, Amman is not sure. Amman used to work as a supply chain manager for a power-tool company. Back then, it was a huge logistical “pain,” no pun intended, to work with large retailers and to attend to their fulfilment needs. Those retailers used to…
