15. How should the sample size be determined for the survey of question 9?

With roots that go back to before the Great Depression, Marriott International (www.marriott.com) has come a long way from its founding by husband and wife John and Alice Marriott. As of 2011, Marriott had a presence in 68 countries with more than 3,500 properties.
This sustained vast expansion over the last several decades is due in large part to marketing research. Marriott began pioneering segmentation in the hospitality industry by expanding its product offering in the 1980s, both upward and downward in quality from its flagship Marriott brand. Marriott found from focus groups and survey research that it could have many types of hotels serving different market segments, and that these market segments, although all providing the same basic needs, would not compete with each other. Certain brands under the Marriott umbrella serve the business traveler. Courtyard by Marriott, with pricing and scaledback service levels compared to the larger Marriott hotels, is targeted toward the price-sensitive frequent business traveler. Courtyard hotels—said to be designed for business travelers by business travelers—offer high-speed Internet access, ample workspace within the room, and other amenities that are appealing to the business traveler. Fairfield Inns are priced still more modestly to appeal to travelers who are even more price sensitive. Other brands under the Marriott flag, such as the Ramada line, serve more of a family-style vacation market, with a focus toward comfort and affordability.
