On November 14, 2019, Washington University and University of Texas A&M publicly launched their research efforts to collect information on over 10,000 dogs, (see https://dogagingproject.org/ (Links to an external site.)). The objective of this research effort is to collect data from dog owners across the USA to identify factors that may affect the life expectancy of canines. The dependent variable is ‘life expectancy of dogs as measured in years and months. The following variables were collected from dog owners:
a. From the data collected, which variable(s) are best represented by a dummy variable(s)?
b. From the data collected, which variable is least likely to be relevant to the life expectancy of a dog and why?
c. From the data collected, which TWO variables are most likely to positively affect the life expectancy of a dog and why?

What is the explanatory variable and what is the response variable?
Create a scatterplot below (go ahead and enter the data into your calculator first, but draw a beautiful scatterplot).
Does it appear that there is a linear relationship between alcohol consumption and heart attacks? Is there a positive association or negative association?
Compute the linear regression equation and the correlation coefficient.
Interpret the slope and y-intercept in the context of alcohol consumption and heart disease.
Superimpose the regression equation on the scatterplot.
Predict the rate of heart attacks for a country where the average wine consumption is 3 liters/person/year
Would it be appropriate to try to predict the death rate from heart attacks for Estonia where the per capita wine consumption is 15 liters/year? Why or why not?

In 2005, North Inc. acquired an 80% interest in South Co. On the date of acquisition, the book values of South’s asset and liability accounts at that time were considered to be equal to their fair values. No allocations or goodwill resulted from the combination because North’s acquisition value corresponded to the underlying book value of South The following selected account balances were from the individual financial records of these two companies as of December 31, 2019: . North South Sales $ 896,000.00 $ 504,000.00 Cost of Goods Sold 406,000 276,000 Operating Expenses 210,000 147,000 Retained Earnings, 1/1/19 1,036,000 252,000 Inventory 484,000 154,000 Buildings, net 501,000 220,000 Investment income not provided North routinely transfers inventory to South. Of the inventory transferred to South, 30% remained in inventory at the end of 2018 and was sold in the following year. 33.33% of the 2019 intra entity sales remained on hand at the end of 2019 and were sold at the beginning of 2020. More date regarding the intra entity transfers for 2018-2019 are shown below: 2018 2019 North Sales Price to South 130000 165000 North's Cost of Goods Sold to South 104000 132000 Unsold Inventory at end of year 30% 33.33% For the consolidated financial statements for 2018, determine the balances that would appear for the following accounts: a) Cost of Goods Sold; b) Inventory; and c) Net income attributable to the noncontrolling interest.

1,2,3) Assume the US market of sunflower oil was described by the following domestic supply and demand equations:
QDUS = 8000 – 4 P
QSUS = -2000 + 6 P
where QDUS and QSUS represent the quantities demanded and supplied (in tons) and P is the price per ton of sunflower oil (in $).
4) Now add this information:
In 2008, China entered into the World Trade Organization and became the largest importer of US sunflower oil. Assume the Chinese import demand for sunflower oil from the US in 2008 was
QDCHINA = 20000 – 10 P
1) What was the market (equilibrium) price of sunflower oil?
2) Using your work in question 1, what was the market (equilibrium) quantity of sunflower oil?
3) Using your work in questions 1 and 2, what were revenues for the suppliers of sunflower oil?
4) Given this information, what was the new equilibrium price of sunflower oil in 2008? (Hint: what is the total demand for US sunflower oil?)
5) Given the price you calculated in the previous question, what was the equilibrium total quantity demanded?
6) Given your answers in the previous 2 questions, how much of the new equilibrium quantity was consumed in the US (i.e., US quantity demanded given the new equilibrium price)?
7) Given your answers in the previous three questions, how much sunflower oil did China purchase from US producers? (i.e., China quantity demanded)
8) Given your calculations in questions # 4 and #5, what were US sunflower oil producer revenues?

1. Identify a struggling company that could benefit from market penetration, market development, or product development. What might you advise this company’s executives to do differently?
2. Some universities have used vertical integration by creating their own publishing companies. The Harvard Business Press is perhaps the best-known example. Are there other ways that a university might vertically integrate? If so, what benefits might this create?
3. Studies have shown that executives’ pay increases when their firms gets larger. To what extent do you think executive pay plays in diversification decisions?
4. What might executives do to keep employees within dog units motivated and focused on their jobs?
