The results of a 2013 Adobe system study on retail apps and buying habits reveal insights on perceptions and attitudes towards mobile shopping using retail apps and browsers, providing new direction for retailers to develop their digital published strategies (adobe.ly/11gt8Rq). Increased consumer interest in using shopping application means retailers must adapt to meet rising expectation for specialized mobile shopping experiences. The results indicate that tablet user (55%) are almost twice as likely as smartphone users (28%) to use their device to purchase and services. The findings also reveal that retails and catalog apps are rapidly catching up to mobile browsers as a viable shopping channel: nearly half of all mobile shoppers are interested in using apps instead of a mobile browser (45% of tablet shoppers and 49% of smartphone shoppers). The research is based on an online survey with a sample of 1,003 consumers. Identify potential concerns with coverage, nonresponse, sampling, and measurement errors.

- Suppose you are conducting a study about how the average U.S. worker spends time over the course of a workday. You are interested in how much time workers spend per day on personal calls, e-mails, 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 U.S. 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 82 full-time workers in the United States and ask about personal calls, e-mails, 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 break time per day from the most recent census is 29.6 minutes, with a standard deviation of 16.0 minutes. Your sample of 82 U.S. workers…arrow_forwardPursuing an MBA is a major personal investment. Tuition and expenses associated with business school programs are costly, but the high costs come with hopes of career advancement and high salaries. A prospective MBA student would like to examine the factors that impact starting salary upon graduation and decides to develop a model that uses program per-year tuition as a predictor of starting salary. Data were collected for 37 full-time MBA programs offered at private universities. The data are stored in the accompanying table Use the least-squares method to determine the regression coefficients b0 and b1.arrow_forwardMany research studies have been conducted to examine how different organizations are on implementing knowledge management processes. For example, studies have proved that larger firms have more resources to utilize, and so they have taken more efforts to implement knowledge management processes. The Journal of Business Research (Aug. 2014) published a study discussing the relationship between knowledge management processes and organizational performance. The table below shows the percentage of different size of firms participated in the study. These firms have been classified in terms of number of employees working. Need step-by-step procedure to answer each question. Randomly select one of the participated company from this study. Let x be the number of employees working in the company. Write the probability distribution of this x. What is the probability that the selected company employs more than 50 employees? Find E(x) and σ. Interpret the result.arrow_forward

When survey data indicated that the coffee company needed to improve its package-sealing process, an experiment was conducted to determine the factors in the bag-sealing equipment that might be affecting the ease of opening the bag without tearing the inner liner of the bag. One factor that could affect the rating of the ability of the bag to resist tears was the plate gap on the bag-sealing equipment. Data were collected on 19 bags in which the plate gap was varied. A) Assuming a linear relationship, use the least-squares method to find the regression coefficients b0 and b1. Interpret the meaning of the slope, b1,in this problem. Choose the correct answer below. A.For each increase of one in the tear rating, the plate gap is expected to increase by b1 units. B. The approximate tear rating when the plate gap is 0 units is b1. C. The approximate…arrow_forwardSociologists argued that women on average earn less than men as women often choose to work less hours. They further suggest that the choice of hours worked may be driven by various factors such as age, childcare needs, occupation choice and flexibility. To investigate the relation between hours worked and income earned by Australian men and women, a researcher plans to survey a sample of individuals across the country. First, the researcher categorised the data into six location groups and six occupation groups, and calculated the frequencies given below. Frequency tables Location Occupation Location category Frequency Occupation category Frequency Location group A 5 Occupation group 1 4 Location group B 7 Occupation group 2 26 Location group C 12 Occupation group 3 15 Location group D 25 Occupation group 4 12 Location group E 10…arrow_forward
- A global research study found that the majority of today's working women would prefer a better work-life balance to an increased salary. One of the most important contributors to work-life balance identified by the survey was "flexibility," with 49% of women saying that having a flexible work schedule is either very important or extremely important to their career success. Suppose you select a sample of 100 working women. Answer parts (a) through (d). ... a. What is the probability that in the sample fewer than 55% say that having a flexible work schedule is either very important or extremely important to their career success? 0.8849 (Round to four decimal places as needed.) b. What is the probability that in the sample between 46% and 55% say that having a flexible work schedule is either very important or extremely important to their career success? 0.6108 (Round to four decimal places as needed.) c.

- Absenteeism: Absenteeism can be a serious employment problem. It is estimated that absenteeism reduces potential output by more than 10%. Two economists launched a research project to learn more about the problem. They randomly selected 100 organizations to participate in a 1-year study. For each organization, they recorded the average number of days absent per employee and several variables thought to affect absenteeism. Management’s goal here is to analyze the data and determine which factors may be helpful in predicting absenteeism. Now let us build a model to predict absenteeism based on key independent variables available in this dataset; wage, PctPT, PctU, Av Shift and U/MRel The following down below is the correlation matrix between absenteeism and potential independent variables. Why are the variables AvShift and U/MRel excluded from this correlation matrix? Which variable in the matrix is likely to provide the best simple linear regression model and why?
