Hsci 2117: Problem Set 6 – Chi-Squared and Regression

Hsci 2117: Problem Set 6 – Chi-Squared and Regression

A pharmaceutical company develops a new drug that helps obese patients who are not currently diabetic avoid contraction of diabetes. The company conducts a trial splitting a sample of 135 patients into two groups: a drug group, and, a placebo group. They then monitored the patients for 5 years and noted how many patients in each group contracted diabetes. The company wants to conduct a Chi-Squared test for Independence to assess whether their new drug has any effect on the contraction of diabetes amongst obese patients at the 95% confidence level. Use this data to answer questions 1-3.

Number of Patients Drug Placebo
Contracted diabetes 56 20
Did not contract diabetes 34 25

 

  1. Identify the correct critical value, . (10%)
  2. Calculate the test statistic, . (10%)
  3. The company statistician tells you that the p-value of the test is 0.0496. Compare the test statistic to the critical value. Compare the p-value to alpha. Compare the percentage of patients on the drug who contracted diabetes, to the percentage of patients on the placebo who contracted diabetes. Is there statistically significant evidence to suggest that the drug is effective in preventing the contraction of diabetes? Explain why or why not. (20%)

 

An occupational therapist hypothesizes that there is a linear relationship between the number of years her patients spent in a desk job and the number of weeks it takes to complete therapy.

Desk Job Yrs (j) 29.9 20 14.2 20.6 12.1 23.4 25.4 24.7 13.2 27.6
Therapy Wks (t) 12 8 6 7 5 11 9 11 5 12

 

  1. Calculate and interpret the pearson’s correlation coefficient between the variables J and T, , and the coefficient of determination between the variables J and T, . (20%)
  2. Determine the coefficients of the least squares regression line for the following model between years in a desk job and weeks in therapy : (20%)
  3. Use the least-squares regression line to predict the expected number of weeks of therapy needed for a patient who has spent 22.5 years in a desk job, . (20%)

Ethics and Social Responsibility in Business

In marketing as in other aspects of business, it is critical that professionals make sure to act in an ethical manner both legally and socially. In this age of interconnectedness, one unethical move can become an Internet video or comment that spreads rapidly, not just locally but potentially throughout the world. From a marketing standpoint, it is critical to take into account the impact of an organization’s decisions on other people and the environment.

However, how you communicate the expected conduct required in a business is as important as the ethical expectations themselves. Most companies have a written Code of Conduct as well as other corporate statements that communicate the expected behavior and values of the firm.

In this Assignment, you will engage in the development of the following professional competencies:

  • Make ethical decisions and solve problems
  • Written Communication

In this Assignment you will read the Cengage® Case Study: “Barclays Bank: Banking on Ethics” and then respond to the checklist items in a critical essay based on a scenario.

CEMEX is a Mexican company that has become a major international competitor in cement while maintaining a higher level of profitability than other, long-established majors. CEMEX’s superior profitability supplies a basis for discussing the sources of superior performance in a global context. In addition, the wide array of benefits that CEMEX derives from its operations in different countries broadens conventional notions of why firms globalize. After you review the case, prepare a response (4-5 pages) to the following case questions: 1) What benefits have CEMEX and the other global competitors in cement derived from globalization? More broadly, how can cross-border activities add value in an industry as apparently localized as cement? 2) How specifically has CEMEX managed to outperform its leading global competitors in the cement industry? Please focus on comparing it with Holderbank, which is the other large competitor principally focused on cement. What do this comparison and the other data in Exhibits 4-8 suggest about the competitive game being played out among the major international companies? 3) What accounts for the sequence in which CEMEX entered foreign markets? How do the markets it has entered recently compare with the markets that it entered early on? 4) What recommendations would you make to CEMEX regarding its globalization strategy going forward? In particular, what kinds of countries should it focus its future expansion on?

Scenario: You have just graduated from your current University with your Bachelor’s Degree. You have decided either to seek a promotion at your current work, explore new career opportunities, or open your own business and are using your marketing knowledge to position yourself for career growth. 

 

Develop a 950-word response to the following 3 bullets using the scenario above:

  • Provide a definition of marketing from the American Marketing Association. Define the customer value proposition. Discuss the differences between the marketing process and advertising, the goals of creating a strong customer value proposition, and the unique relationship that exists between company and customer.
  • Use your workplace, a company you would like to work for, or an entrepreneurial vision and apply the concepts of the customer value proposition and relationship marketing to their operations. Introduce who the company, or business idea is and what they do. Provide examples demonstrating how the company uses these concepts successfully. Are there any ways they can improve in these areas? How?
  • Determine how your own personal brand links to the organization’s customer value proposition. Discuss ways you can integrate a customer value proposition and use relationship marketing to position yourself the best. Please share examples to illustrate your thoughts and reasoning.

Cite a minimum of two peer-reviewed sources with at least one coming from the textbook (Marketing 13th edition Roger Kerin and Steven Hartley)
