1.15 Performance-based logistics. In industry, performance-based logistics (PBL) strategies are increasingly popular ways to reduce cost, increase revenue, and attain customer satisfaction. The Journal of Business Logistics (Vol. 36, 2015) used the opinions of a sample of 17 upper-level employees of the U.S. Department of Defense and its suppliers to determine the factors that lead to successful PBL projects. The current position (e.g., vice president, manager [mgr.]), type of organization (commercial or government), and years of experience were measured for each employee interviewed. These data are listed below. Identify each variable measured as producing quantitative or qualitative data.

- A mail-order catalog business that sells personal computer supplies, software, and hardware maintains a centralized warehouse for the distribution of products ordered. Management is currently examining the process of distribution from the warehouse and has the business objective of determining the factors that affect warehouse distribution costs. Currently, a handling fee is added to the order, regardless of the amount of the order. Data that indicate the warehouse distribution costs and the number of orders received have been collected over the past 24 months and can be seen below: Months Distribution Cost ($thousands) Number of Orders 1 52.95 4015 2 71.66 3806 3 85.58 5309 4 63.69 4262 5 72.81 4296 6 68.44 4097 7 52.46 3213 8 70.77 4809 9 82.03 5237 10 74.39 4732 11 70.84 4413 12 54.08 2921 13 62.98 3977 14 72.30 4428 15 58.99 3964 16 79.38 4582…arrow_forwardA consulting group recently conducted a global survey of product teams with the goal of better understanding the dynamics of product team performance and uncovering the practices that make these teams successful.

An academic advisor wants to predict the typical starting salary of a graduate at a top business school using GMAT score of the school as a predictor variable. The results of a simple linear regression of SALARY versus GMAT using the 25 data points are shown below. Is there sufficient evidence to suggest there is a linear relationship between SALARY and GMAT at the 5% level of significance? ----------------------------------------------------------------------------------- a = -92040 b = 228 s = 3213 r2 = .66 r =…arrow_forward
- You are on the board of directors for Sew and Tell, an up and coming apparel brand focusing on producing t-shirts with a positive message.

- The manager Concerned about her current customer base, manager Andersen started to think of factors that might affect the attractiveness of an auditing firm. Of course, the service quality provided and the fees charged by the auditor seem two important factors. Next, she decides that the reputation of the auditing firm also needs to be included in the framework as an independent variable. As illustrated by the dramatic effects of recent auditing scandals, reputation seems especially important for large auditors (i.e., auditing firms that are large in size). Finally, manager Andersen also thinks that the proximity of the auditing firm to the customer is another variable to be included as an independent variable. Proximity very likely affects the possibility for the client to personally meet with the auditors on a regular basis and she knows from her own contact with customers that they perceive personal interactions as quite important. Consider the above scenario shown; answer the…arrow_forwardSocial 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_forwardThe more costly and time-consuming it is to export and import, the more difficult it is for local companies to be competitive and to reach international markets.
