Question 8

Tata Motors of India is marketing a new vehicle that retails for only $2,200. The vehicle will carry two persons and has a body made of fiberglass. It is designed in component parts so that if a part is broken, you can easily remove the part and replace it with a new one ordered from Tata. Tata realizes that it will take some time for countries to allow the small vehicle on public roads due to the varying safety requirements. However, Tata sees an immediate market among business firms who need inexpensive yet reliable vehicles to transport personnel around large manufacturing or warehousing facilities. One Tata manager stated: "Ninety percent of the time, company cars are used to transport only one or two persons and much of their travel is confined to the plant premises." "The new Tata vehicle will not replace the large company cars but can reduce the number of company cars a firm must buy by a substantial amount, thus saving tremendous amounts of money." Executives at Tata are interested in a sales estimate in Great Britain, their first targeted market outside of India. They will construct a sales forecast based upon a survey of companies and they know that demand will vary substantially, depending on the size of the company. Small firms will not want any vehicles, medium-sized firms may want about 5 or 10 vehicles, and large firms may want 20 to 100 vehicles. Secondary data is available that allows Tata to identify all firms in Great Britain and to know the size of the firm. If a survey is conducted to predict demand for the new Tata vehicle among business firms, which of the following sampling methods would be most appropriate?

Question 15

Eddie Livingston is president of Community Credit, a credit union with several locations. Eddie has been exploring the impact of service satisfaction with financial performance and is convinced that he can improve the credit union's returns if he can improve customer satisfaction. He has been contemplating a proposal from Re$earch Inc., a research firm that specializes in the financial services industry, to begin a program of improving customer satisfaction. Tanner has recommended a survey of customers to establish gaps in service as perceived by the customers. Eddie knows that the credit union has a list of all the customers and that this information is on an electronic database complete with mailing addresses and, for those having Internet service, email addresses. At the next meeting, Eddie expresses concern that sending a questionnaire to all bank customers is an inconvenience to them and he doesn't want to negatively impact customer satisfaction. The researchers from Re$earch assure Eddie that they can get the needed information for as few as a couple of hundred customers and that the results will be representative of all his credit union customers. Which of the following sample methods would most likely be appropriate?

Accepted Answer

A)  simple random sample 
B)  judgment sample 
C)  stratified sample 
D)  cluster, area sample
