Chapter 10.2, Problem 10.10ACB
Offshoring companies. “Offshoring” is a term that describes a company’s practice of relocating jobs and/or production to another country to reduce labor costs. The Journal of Applied Business Research (January/February 2011) published a study on the phenomenon of offshoring and how prevalent it is worldwide. The article included the results from a recent survey of CEOs at U.S. firms, where each CEO was asked about his or her firm’s position on offshoring. A summary of the results (similar to the actual study) is shown in the accompanying table.
Firm’s Position | Number of Firms |
Currently offshoring | 126 |
Not currently offshoring, but plan to do so in the future | 72 |
Offshored in the past, but no more | 30 |
Offshoring not applicable | 372 |
Total | 600 |
- a. Identify the qualitative variable of interest (and its levels) for this study.
- b. Are the proportions of U.S. firms in the four offshoring position categories significantly different? Conduct the appropriate chi-square test using α = .05.
- c. Construct a 95% confidence interval for the proportion of U.S. firms who are currently offshoring. Interpret the result.

Government economic studies reveal that young adults, not middle-aged or older adults, are having the most difficult time in today’s economy. Although the nation’s labor market shows a decline in the unemployment rate, the percentage of young adults, ages 18 to 24, currently employed (54 percent) is at the lowest level since the government data collection began in 1948. If you were working for a national survey organization doing a general public survey of young adults and older adults, what topics and questions would you design into your survey to elaborate on this finding?
“The rapid growth of video game popularity has generated concern among practitioners, parents, scholars, and politicians,” wrote researchers Hope M. Cummings and Elizabeth A. Vandewater. In their study, Cummings and Vandewater measured the time adolescents spent playing video games as well as time spent doing other activities, such as interacting with family and friends, reading or doing homework, or playing sports. [Source: Cummings, H., & Vandewater, E. (2007). Relation of adolescent video game play to time spent in other activities. Archives of Pediatrics & Adolescent Medicine, 161(7), 684–689.]
After reading about the study conducted by Cummings and Vandewater, you decide to conduct a similar study among a sample of 10 teenage girls. You ask the girls to keep a log of their activities for a day. You want to test whether the amount of time girls spend playing video games is correlated with the amount of time they read for pleasure. You realize that because some of the…

During their 8th- and 11th-grade school years, students in the Ranger School District take standardized achievement tests designed to assess their language and math skills. The superintendent receives a report showing how Ranger students compare with those in many other school districts across the nation. The superintendent discusses the results with the school principals. (a) Classify the research as one of the following: Quantitative/descriptive Quantitative/correlational Quantitative/experimental Quantitative/quasi-experimental Qualitative Mixed methods, and then (b) Identify one or more conclusions that might reasonably be drawn from this study and, if relevant, one or more conclusions that cannot be drawn from the studyarrow_forwardSuppose you are conducting a study about how the average US worker spends time over the course of a workday. You are interested in how much time workers spend per day on personal calls, emails, and social networking websites, as well as how much time they spend socializing with coworkers versus actually working. The most recent census provides data for the entire population of US workers on variables such as travel time to work, time spent at work, and break time at work. The census, however, does not include data on the variables you are interested in, so you obtain a random sample of 102 full-time workers in the United States and ask about personal calls, emails, and so forth. You are curious about how your sample compares with the census, so you also ask the workers the same questions about work that are asked in the census. Suppose the mean travel time to work from the most recent census is 24.1 minutes, with a standard deviation of 4.5 minutes. Your sample of 102 US workers…arrow_forward

During that time, Westminster provided a choice of several pre-designed investment packages. Westminster classified the packages into three categories according to riskiness. We're interested in the possible relationship between the age of an investor and the riskiness of the investment package she chose. So, there are two variables under consideration: age of Westminster investor ("under 35", "35-49", or "50+") and riskiness of investment choice ("risky", "moderate/mixed", or "conservative"). The contingency table below gives a summary of the information released by Westminster regarding age and riskiness of investment package for a random sample of 150 investors. Each cell of the table contains three numbers: the first number is the observed cell frequency (fo); the second number is the expected cell frequency (f) under the assumption that there is no relationship between the two…arrow_forward
- Social media provides an enormous amount of data about the activities and habits of people using social platforms like Face book and Twitter. The belief is that mining that data provides a treasure trove for those who seek to quantify and predict future human behavior. A marketer is planning a survey of Internet users in the United States to determine social media usage. The objective of the survey is to gain insight on these three items: key social media platforms used, frequency of social media usage, and demographics of key social media platform users. a. For each of the three items listed, indicate whether the variables are categorical or numerical. If a variable is numerical, is it dis crete or continuous? b. Develop five categorical questions for the survey. c. Develop five numerical questions for the survey.arrow_forwardWestminster Financial has released a summary of investment package information from the past fiscal year.

- A health policy economist interested in investigating the relationship between the cost of prescription drugs in Canada and the cost of prescription drugs in the United States has information from a random sample of 48 prescription drugs sold in both countries. For each of these drugs, the economist is examining two pieces of information: the average cost of a one-month supply of the drug in Canada, and the average cost of a one-month supply of the drug in the United States. For the sample of drugs examined, the sample correlation coefficient r relating these two pieces of information is 0.33. Test for a significant linear relationship between the two variables average prescription drug cost in Canada and average prescription drug cost in the United States by doing a hypothesis test regarding the population correlation coefficient p.

Then complete the…arrow_forwardRebecca Chory, Ph.D., now an associate professor of communication at West Virginia University, began studying the effect of such portrayals on patients' attitudes toward physicians. Using a survey of 300 undergraduate students, she compared perceptions of physicians in 1992—the end of the era when physicians were shown as all-knowing, wise father figures—with those in 1999, when shows such as ER and Chicago Hope (1994–2000) were continuing the transformation to showing the private side and lives of physicians, including vivid demonstrations of their weaknesses and insecurities. Dr. Chory found that, regardless of the respondents' personal experience with physicians, those who watched certain kinds of television had declining perceptions of physicians' composure and regard for others. Her results indicated that the more prime time physician shows that people watched in which physicians were the main characters, the more uncaring, cold, and unfriendly the respondents thought physicians…arrow_forwardNumerous studies have shown that watching too much television hurts children’s school grades. Others have argued that television is not necessarily a bad thing for children (Mail Online; July 2009). Like books and stories, television not only entertains, it also exposes a child to new information about the world. While watching too much TV is harmful, a little bit may actually help. Suppose a researcher gathers information on the grade point average (GPA) of 28 middle school children and the number of hours of TV they watch per week.
