Coupon user study. A hot topic in marketing research is the exploration of a technology-based self-service (TBSS) encounter, e.g., ATMs, automated hotel checkout, online banking, and express package tracking. Marketing Professor Dan Ladik (University of Suffolk) investigated a customer’s motivation to use a TBSS developed for a firm’s discount coupons. The coupon users received the coupons in one of three ways—mail only (nontechnology user), Internet only (TBSS user), and both mail and Internet. One of the variables of interest in the study was Type of coupon user. In particular, the professor wants to know if the true proportions of mail only, Internet only, and both mail and Internet users differ. In a sample of 440 coupon users, the professor discovered that 262 received coupons via only mail, 43 via only the Internet, and 135 via both mail and Internet Conduct the appropriate analysis for the professor. Use α = .01.

A variety of stores offer loyalty programs. Participating shoppers swipe a bar-coded tag at the register when checking out and receive discounts on certain purchases. Stores benefit by gleaning information about shopping habits and hope to
encourage shoppers to spend more. A typical Saturday morning shopper who does not participate in this program spends $150 on her or his order. In a sample of 80 shoppers participating in the loyalty program, each shopper spent $160 on
average during a recent Saturday, with standard deviations = $40. Is this statistical proof that the shoppers participating in the loyalty program spend more on average than typical shoppers? (Assume that the data meet the sample size
condition.) Complete parts a-d.

A research question of interest is whether financial incentives can improve performance. Alicia
designed a study to test whether video game players are more likely to win on a certain video game
when offered a $5 incentive compared to when simply told to "do your best." Forty subjects are
randomly assigned to one of two groups, with one group being offered $5 for a win and the other
group simply being told to "do your best." She collected the following data from her study:
$5 incentive
"Do your best"
Total

8.

Based on these data, is there a relationship between the incentive and performance, using a = .05?
As the price of oil rises, there is increased worldwide interest in alternate sources of energy. The Financial Times/Harris Poll surveyed people in six countries to assess attitudes toward a variety of alternate forms of energy. The data in the following table are a portion of the poll's findings concerning whether people favor or oppose the building of new nuclear power plants.

The director of computer technology in Emerson School District wants to gather information about the use of technology-based instruction in language arts and literature classes in the district's middle schools and high schools. For her study, the director identifies five of the top teachers in these content areas. She visits and observes each teacher's classes on three different days and subsequently interviews each teacher. Then she summarizes the ways that these teachers incorporate the use of technology into their lessons and their students' activities.

Historical data suggests that the Atlanta flight is “on time” 90% of the time, the Dallas flight is “on time” 95% of the time, and the Chicago flight is “on time” 80% of the time. Furthermore, historical data suggests that the three flights are independent with respect to on time behavior. Define the sample space for this random experiment.

- In the book Business Research Methods (5th ed.), Donald R. Cooper and C. William Emory discuss a market researcher for an automaker who is studying consumer preferences for styling features of larger sedans. Buyers, who were classified as "first-time" buyers or "repeat" buyers, were asked to express their preference for one of two types of styling-European styling or Japanese styling. Of 40 first-time buyers, 7 preferred European styling and 33 preferred Japanese styling. Of 60 repeat buyers, 35 preferred European styling and 25 preferred Japanese styling. (a) Set up a contingency table for these data. Buyers First-time Repeat Total European x^2 = Style Japanese Total (b) Test the hypothesis that buyer status (repeat versus first-time) and styling preference are independent at the .05 level of significance.

After completing a college degree, graduates are faced with the important project of finding a job. Options include networking through friends and relatives, pursuing newspaper ads, applying in person, conducting an Internet job search, using a professional employment agency or recruiter, and using a college placement office. Some of these avenues are likely to be much more productive than others. Specifically, networking has been found to be one of the most productive approaches. With networking, a job seeker develops contacts and exchanges information through an informal network of people. One recent survey involved 703 randomly selected subjects who were all working. Among those subjects, 61% said that they found their job through networking (based on data from Taylor Nelson Sofres Intersearch). Another effective approach appeared to be newspaper ads, with 16% of the respondents finding jobs through such ads. Based on these survey…arrow_forwardAn investors association's on-line discount broker survey polls members on their experiences with electronic trades handled by discount brokers. As part of the survey, members were asked to rate their satisfaction with the trade price and the speed of execution, as well as provide an overall satisfaction rating. Possible responses (scores) were no opinion (0), unsatisfied (1), somewhat satisfied (2), satisfied (3), and very satisfied (4). For each broker, summary scores were computed by computing a weighted average of the scores provided by each respondent. A portion of the survey results follow. (Let x1 represent satisfaction with trade price, x2 represent satisfaction with speed of execution, and y represent overall satisfaction with electronic trades.)
