Vibrant Company had $1,020,000 of sales in each of three consecutive years 2016–2018, and it purchased merchandise costing $560,000 in each of those years. It also maintained a $320,000 physical inventory from the beginning to the end of that three-year period. In accounting for inventory, it made an error at the end of year 2016 that caused its year-end 2016 inventory to appear on its statements as $300,000 rather than the correct $320,000.

Required:
1. Determine the correct amount of the company’s gross profit in each of the years 2016–2018.
2. Prepare comparative income statements to show the effect of this error on the company's cost of goods sold and gross profit for each of the years 2016−2018.
  

In 2018 and 2019, Health Canada commissioned two national surveys on the use of cannabis among people aged 20 to 24. They found 175 users out of the 1000 surveyed individuals in 2018 and 230 out of the 1100 sample in 2019.

(a) Test the hypothesis that there has been a change in the proportion of cannabis users in the 20-24 age

group population between 2018 and 2019. Use the critical value approach and a 0.05 level of

significance.

(b) Find the p-value for your result in (a) above.

(c) Calculate a 95% two-sided confidence interval for the true difference using the data provided.

(d) Explain how the p-value and the confidence interval are or are not consistent with your result in

part (a) above.

Assignment Details

Throughout this class, you have been working with a product of your creation that dealt domestically. This week, you will switch gears and address a real company that does global business.

Note: Please refrain from using assignments from other classes that you have taken.

The Analysis

Select a global company of your choice in the service industry. Using your selected global company as the subject matter, research the principles of marketing that impact this organization, and prepare an APA paper with the following:

Describe the main line of business of the company.

Name 4 of the countries in which the company operates.

Explain in detail the implementation of the 4 P marketing mix concept by the company, including the following:

Competition

Target market

Product strategy

Distribution strategy

Communication strategy

Pricing strategy

Describe any differences observed in the implementation of this concept from one country to another.

This assignment will be assessed using additional criteria provided here.

Your report must include a reference list. All research should be cited in the body of the paper. In-text citations and corresponding references should be included in your paper. For more information on APA style, please visit the APA lab. The paper should be written in third person, which means that pronouns like “I,” “we,” and “you” are not appropriate. The use of direct quotes is strongly discouraged.

Your assignment should contain a cover page, an abstract page, and a reference page in addition to the body. The body of the paper should be 3–4 pages in length, starting with a brief 1-paragraph introduction and ending with a short conclusion. The entire submission will be 6–8 pages in length.

Please submit your assignment as a Word document in APA format using the attached template.

Submitting your assignment in APA format means that you will need a minimum of the following:

Title page: Remember to include the running head and the title in all capital letters.

Abstract: This should be a summary of your paper, not an introduction. Begin writing in third person voice.

Body: The body of your paper begins on the page following the title page and abstract page, and it must be double-spaced (be careful not to triple- or quadruple-space between paragraphs). The typeface should be 12-point Times New Roman or 12-point Courier in regular black type. Do not use color, bold type, or italics, except as required for APA headings and references. The deliverable length of the body of your paper for this assignment is 3–4 pages. In-body academic citations to support your decisions and analysis are required. A variety of academic sources is encouraged.

Reference page: References that align with your in-text academic sources are listed on the final page of your paper. The references must be in APA format, using appropriate spacing, hang indention, italics, and upper and lower case as appropriate for the type of resource used. Remember, the reference page is not a bibliography, but it is a further listing of the abbreviated in-text citations that are used in the paper. Every referenced item must have a corresponding in-text citation.

GLOBALIZATION HOMEWORK

This week, we began our exploration of economic globalization by reflecting on the ideologies, policies, and institutions that have informed these processes since the early 1980s. In particular, we have been exploring the dominant ideology of neoliberalism, and its associated set of policies, most commonly known as 'free trade.'

In this discussion, you are asked to consider the pros and cons of 'free trade.' What are the benefits of free trade? What are the costs of free trade? How are these costs and benefits distributed around the globe? Does the dominant framework of 'free trade,' guided by the principles of neoliberal economics, foster or threaten global welfare?

Your original post should be approximately 8 - 10 sentences in length, using proper sentence and paragraph structure, and is worth 3 marks. Incorporate theoretical and empirical details drawn from readings and learning materials to support your ideas

A Gallup poll was conducted in 2010 in which they surveyed people all over the world and found that 44% of adults in the world believe that global warming is a serious threat to themselves and their families. Assume that this is the population proportion of adults worldwide who believe global warming is a threat (p= 0.44), and suppose we repeatedly select random samples of size 250, and ask them the same question.

(a) Find the mean, and standard error, of the sampling distribution of sample proportions for the given n and p.

(b) Use the Empirical Rule to find the interval centered at p that contains approximately 99.7% of all sample proportions.

(c) Suppose that in a random sample of 250 people, 100 say that global warming is a threat. Find the sample proportion � and the z-score for this sample proportion.  

(d) What is the probability that in a random sample of 250 people, 100 or less will say they think global warming is a threat?
