Learn about Business Interview five adults to learn about their jobs and the companies that employ them. Ask questions about their job responsibilities to determine in which main function of business they work. Identify whether the companies that employ them are domestic or global in scope and if they are in the private or public sector. Identify their NAICS classification. Prepare a table using a word processing program to report your findings in an organized manner. Share your findings with classmates in an oral presentation.

Directions Read the following questions. On a separate sheet of paper write the best possible answer for each one.

What is the net worth of a company with assets of $\$ 12,555,000$ and liabilities of $\$ 11,633,000$ ?

A. $\$ 9,200$

B. $\$ 922,000$

C. $\$ 9,265,631$

D. $\$ 24,188,000$

Consider the production of gold during the California gold rush (1848–1888). The production of gold can be modeled by $G(t)=\frac{(25 t)}{\left(t^{2}+16\right)},$ where t is the number of years since the rush began $(0 \leq t \leq 40)$ and G is ounces of gold produced (in millions). Find when the minimum (local and global) gold production occurred. What was the amount of gold produced during this minimum?

Global Foundries (GF), a privately held company that invests in companies producing essential components for high-volume data storage, is valued at $4.0 billion dollars. A computer company that wants to get into cloud computing is considering the purchase of GF, but because of the uncertain economy, it would prefer to purchase an option that will allow it to buy the company for up to 1 year from now at a cost of$4.3 billion. What is the maximum amount the company should be willing to pay for the option if its MARR is 9% per year?

In 2015 Kraft Foods Group Inc., merged with H.J. Heinz Co. to form the world's fifth-largest food and beverage company. Heinz is a global brand, famous for its tomato ketchup, sauces, soups, beans, pasta and infant foods. Kraft is one of North America's largest consumer packaged food and beverage companies, with annual sales revenues of more than $\$ 18$ billion and over 22000 employees in the USA. Examine the possible reasons for the merger between Kraft and Heinz.

A Ford Taurus driven 15,000 miles a year will use about 715 gallons of gasoline compared to a Ford Explorer that would use $940$ gallons. About $19.7 \mathrm{~lbm}$ of $\mathrm{CO}_{2}$. which causes global warming, is released to the atmosphere when a gallon of gasoline is burned. Find the extra amount of $\mathrm{CO}_{2}$ production a man is responsible for during a $5$-year period if he trades his Taurus for an Explorer.

Carbon dioxide $\mathrm{CO_2}$ is the gas that is mainly responsible for global warming (the greenhouse effect). The burning of fossil fuels is a major cause of the increased concentration of $\mathrm{CO_2}$ in the atmosphere. Carbon dioxide is also the end product of metabolism. Using glucose as an example of food, calculate the annual human production of $\mathrm{CO_2}$ in grams, assuming that each person consumes $5.0 X 10^2 g$ of glucose per day. The world's population is $7 .0$ billion, and there are $365$ days in a year.

In an attempt to assess total daily travel taxes in various cities, the Global Business Travel Association conducted a study of daily travel taxes on lodging, rental car, and meals (GBTA Foundation website, October 30, 2012). The data contained in the DATA file named Travel Tax are consistent with the findings of that study for business travel to Chicago. Assume the population standard deviation is known to be $8.50 and develop a$95\%$ confidence interval of the population mean total daily travel taxes for Chicago.

In 2015 Kraft Foods Group Inc., merged with H.J. Heinz Co. to form the world's fifth-largest food and beverage company. Heinz is a global brand, famous for its tomato ketchup, sauces, soups, beans, pasta and infant foods. Kraft is one of North America's largest consumer packaged food and beverage companies, with annual sales revenues of more than $\$ 18$ billion and over 22000 employees in the USA. Define the term merger.

Through their Roper Reports Worldwide, GfK Roper conducts a global consumer survey to help multinational companies understand different consumer attitudes throughout the world. Within 30 countries, the researchers interview 1000 people aged 13–65. Their samples are designed so that they get 500 males and 500 females in each country. (www.gfkamerica.com) a) Are they using a simple random sample? Explain. b) What kind of design do you think they are using?

So-called greenhouse gases, which contribute to global warming, have a dipole moment or can be bent or distorted during molecular vibration into shapes that have a temporary dipole moment. Based on this, which of the following gases are greenhouse gases: $\mathrm{N}_2, \mathrm{O}_2$, $\mathrm{O}_3, \mathrm{CO}, \mathrm{CO}_2, \mathrm{NO}_2, \mathrm{~N}_2 \mathrm{O}, \mathrm{CH}_4, \mathrm{CFCl}_3$ ?

The Gallup Poll interviewed 1022 randomly selected U.S. adults aged 18 and older, March 7-10, 2013. Gallup reports that when asked whether respondents thought that global warming was due primarily to human activities, $57 \%$ of respondents said it was. If you can't tell, then say so-this often happens when we read about a survey.

f) Any potential sources of bias you can detect and any problems you see in generalizing to the population of interest

Gallup found in 2013 that 58% of Americans worry a great deal or a fair amount about global warming, up from 55% in 2012. Results for this Gallup poll were based on telephone interviews performed on March $7-10,2013$, with a random sample of 1022 adults, aged 18 and older, living in the United States. Does the increase from 2012 to 2013 show a substantial increase in concern?

e) Do you think this difference is meaningful? Explain.

According to Global Research News (Mar. 4, 2014), one-fourth of all rough diamonds produced in the world are blood diamonds. (Any diamond that is mined in a war zone - often by children - in order to finance a warlord's activity, an insurgency, or an invading army's effort is considered a blood diamond.) Also, 90% of the world's rough diamonds are processed in Surat, India, and of these diamonds, one-third are blood diamonds. Find the probability that a rough diamond is not a blood diamond.
