Design a database for an automobile company to provide to its dealers to assist them in maintaining customer records and dealer inventory and to assist sales staff in ordering cars. Each vehicle is identified by a vehicle identification number (VIN). Each individual vehicle is a particular model of a particular brand offered by the company (e.g., the XF is a model of the car brand Jaguar of Tata Motors). Each model can be offered with a variety of options, but an individual car may have only some (or none) of the available options. The database needs to store information about models, brands, and options, as well as information about individual dealers, customers, and cars. Your design should include an E-R diagram, a set of relational schemas, and a list of constraints, including primary-key and foreign-key constraints.

Please explain in extensive detail:

b. explain why it is or is not appropriate to use the procedures to compute a 95% confidence interval for the true mean number of friends for Facebook users at this large University.

c. find the 95% confidence interval for the true mean number of friends for Facebook users at this large University.

Assume that a welfare program pays $200 per week if a person does not work and reduces the welfare benefit of dollar for dollar with earnings. Assume that the individual does not have any other non wage income. Also assume that the individual has a market wage rate of $10/ hour. Assume a maximum of 120hours of leisure per week (T= 120/ week).

What is the breakeven level of earnings under the program? What is the breakeven level of hours of work under the program?

Suppose that in the absence of the program, the person would work 20 hours per week. What does the program have on the individuals hours of work? USE A GRAPH (NO EXCEL) TO SHOW ILLUSTRATE THE ANSWER.

Suppose that in the absence of the program, the person would work 40 hours per week. What does the program have on the individuals hours of work? USE A GRAPH (NO EXCEL) TO SHOW ILLUSTRATE THE ANSWER.

Answer questions 1-3 above if the program reduced benefits at the rate of 50 center for every dollar earned rather than dollar for dollar.

Scott and Allison are married and file a joint tax return. Scott is a graduate student who works part time and earned $15,000 in 2015. He is not eligible to participate in his employer’s retirement plan because he is a part-time worker. Allison is a high school teacher who earned $60,000 in 2015 and is an active participant in the school district’s retirement plan. Assume you are a financial planner and the couple asks for your advice. Based on the preceding facts, answer each of the following questions.

a. Is Scott eligible to establish and deduct contribu-tions to a traditional IRA? Explain your answer.

b. Is Allison eligible to establish and deduct contributions to a traditional IRA? Explain your answer.
c. Assume that Scott graduates and the couple’s modi-fied adjusted gross income is $130,000 in 2015. Both Scott and Allison participate in their employers’ retirement plans. Can either Scott or Allison, or both, establish a Roth IRA? Explain your answer.
d. Explain to Scott and Allison the advantages of a Roth IRA over a traditional IRA.

In April 2015, CEO Dan Price of Gravity Payments made a shocking announcement. Price, who is also founder and co-owner of Gravity, decided to cut his own salary by 93 percent, and then to use that money—along with a big chunk of corporate profits— to ensure that every single one of his employees makes a minimum of $70,000.1

The news was certainly welcomed by Gravity’s employees. (For the lowest-paid employees, the raise to $70k meant a doubling of their salaries.) And Price was widely applauded by commentators and on social media.

Price’s move was especially noteworthy in an era in which many CEOs have been criticized for accepting astronomically high levels of pay. In a 2015 article on executive compensation, Bloomberg.com reported,2 for example, that Elon Musk, the entrepreneurial CEO of Tesla Motors Inc., earned just over $100 million in 2014. But that’s far from the high end of executive compensation: The same article noted that Nicholas Woodman, CEO of GoPro Inc., had earned a whopping $285 million that year. Criticism of CEO pay has not focused solely on the absolute amount earned, but also on the ratio of CEO pay to what those CEOs’ employees are paid. According to the Bloomberg article, “The CEOs of 350 Standard & Poor’s 500 companies made 331 times more than their employees in 2013.”

Some people defend high levels of pay for CEOs, pointing out that the highest levels of compensation are achieved through stock options, which means that CEOs do well only when the value of the company’s stock goes up, a sign that the CEO is actually doing a good job. Others, however, are skeptical. As the Bloomberg article points out, “Stock options, once believed to align executives with shareholders because they appreciate when the stock price rises, are now derided for encouraging short-term financial engineering at the expense of long- term planning.” In other words, stock options encourage CEOs to find short-term ways to boost stock prices (such as reducing costs by cutting employees), even if those moves aren’t in the long-term interests of the company and its shareholders.

Let’s turn back to Price’s decision. Different people had different reactions to the decision. Some applauded it as a move toward justice or fairness in compensation. Others thought it was a savvy business move, aimed at producing better outcomes for Gravity Payments by motivating employees and gaining free publicity for the company. Still others thought it spoke well of Price’s character; to them, Price looked like what a good CEO ought to look like, in comparison to the greedy CEOs of so many other companies.

questions:

1. Do you think Dan Price is a hero? Why or why not?

2. Are there any further facts that you would want to know before making a judg- ment about this case?

3. GravityPaymentsisprivatelyownedbyDanPriceandhisbrother.IfGravitywere a publicly traded company with thousands of shareholders, would that change your view about the ethics of his decision? If so, in what way?

4. If you were an employee at Gravity Payments, already making $70,000, how would you feel about employees who made half what you make suddenly mak- ing the same amount as you?
