You work for a small advertising agency in Greengrass, N.Y. The agency’s principal
advertising clients are automobile dealers and automobile repair shops. The agency has a good
record of placing advertisements for its clients in both real-space and on the internet.
Last week, you were considering buying a used car, and you found a web-site called
“CarValues.com.” The web site contains a database of information about used vehicles on the
market. The (searchable) database contains dealer-written factual descriptions of the make,
model, color and condition of the vehicle; the number of miles on the vehicle; how long the
vehicle has been on the market; and the price history of the vehicle (what it was originally
offered for, and any subsequent price reductions).
The web site was very helpful to you as a consumer. The data base also contained
information about past used-car sales in the area for the prior 6 months. The formatting on
CarValues.com was not good, and the interface was not user-friendly. You are confident the
developers who work for your company would have created a more user-friendly website.
When you got to work on Monday, a light bulb went on in your head. Why don’t we
create a car-selling website for our advertising clients? They would love it. All we need is a
database to start with. And one is available – right there on the internet, at CarValues.com. So,
you go back and check. There was no Terms of Use Agreement!!! Their data is right there for the
taking. Once we have the data, our company can update the information on our own going
forward without having to copy it from CarValues. But being able to use the CarValues
information would help us get started right away.
Your technician says he can capture all the existing data in minutes. Then your
organization can do the updating going forward as new cars come on the market and existing
ones are sold.
You mention your idea to, Carla Speil, the head of the agency at lunch. She is intrigued.
But is it legal? What are the potential consequences if CarValues.com finds out? ...She sees the
rewards.... But what are the risks? “Should we do it?,” she asks. Unusual for an advertising
executive, she seemed concerned about the ethics.
Write a one-page memo, Ms. Speil says, answering her questions.

Lon Timur is an accounting major at a midwestern state university located approximately 60 miles from a major city. Many of the students attending the university are from the metropolitan area and visit their homes regularly on the weekends. Lon, an entrepreneur at heart, realizes that few good commuting alternatives are available for students doing weekend travel. He believes that a weekend commuting service could be organized and run profitably from several suburban and downtown shopping mall locations. Lon has gathered the following investment information.

(a)

Determine the annual (1) net income and (2) net annual cash flows for the commuter service. (Round answers to 0 decimal places, e.g. 125.)

(b)

Compute (1) the cash payback period and (2) the annual rate of return. (Round answers to 2 decimal places, e.g. 10.50.)

(c)

Compute the net present value of the commuter service. (Round answer to 0 decimal places, e.g. 125. If the net present value is negative, use either a negative sign preceding the number eg -45 or parentheses eg (45). For calculation purposes, use 5 decimal places as displayed in the factor table provided.)

1. Mean entry-level salaries for college graduates with mechanical engineering degrees and electrical engineering degrees are believed to be approximately the same. A recruiting office thinks that the mean mechanical engineering salary is actually lower than the mean electrical engineering salary. The recruiting office randomly surveys 44 entry level mechanical engineers and 58 entry level electrical engineers. Their mean salaries were $46,300 and $46,900, respectively. Their standard deviations were $3420 and $4230, respectively. Conduct a hypothesis test at the 5% level to determine if you agree that the mean entry- level mechanical engineering salary is lower than the mean entry-level electrical engineering salary. Let the subscript m = mechanical and e = electrical.
NOTE: If you are using a Student's t-distribution for the problem, including for paired data, you may assume that the underlying population is normally distributed. (In general, you must first prove that assumption, though.)

Part (d)State the distribution to use for the test. (Enter your answer in the form z or t_df where df is the degrees of freedom. Round your answer to two decimal places.)

Part (f)What is the p-value? (Round your answer to four decimal places.)

2.Some manufacturers claim that non-hybrid sedan cars have a lower mean miles-per-gallon (mpg) than hybrid ones. Suppose that consumers test 21 hybrid sedans and get a mean of 31 mpg with a standard deviation of 7 mpg. Thirty-one non-hybrid sedans get a mean of 20 mpg with a standard deviation of three mpg. Suppose that the population standard deviations are known to be six and three, respectively. Conduct a hypothesis test at the 5% level to evaluate the manufacturers claim.

Part (d)State the distribution to use for the test. (Round your answers to two decimal places.)

Part (e)What is the test statistic? (If using the z distribution round your answer to two decimal places, and if using the t distribution round your answer to three decimal places.)

Part (f)What is the p-value? (Round your answer to four decimal places.)

NOTE: If you are using a Student's t-distribution for the problem, including for paired data, you may assume that the underlying population is normally distributed. (In general, you must first prove that assumption, though.)

13–1. Conditions of Performance. The Caplans contract with Faithful Construction, Inc., to build a house for them for $360,000. The specifications state “all plumbing bowls and fixtures... to be Crane brand.” The Caplans leave on vacation, and during their absence, Faithful is unable to buy and install Crane plumbing fixtures. Instead, Faithful installs Kohler brand fixtures, an equivalent in the industry. On completion of the building contract, the Caplans inspect the work, discover the substitution, and refuse to accept the house, claiming Faithful has breached the conditions set forth in the specifications. Discuss fully the Caplans’ claim.

13–8. Reformation. Dr. John Holm signed a two-year employment agreement with Gateway Anesthesia Associates, PLLC. During negotiations for the agreement, Gateway’s president, Dr. Jon Nottingham, told Holm that on completion of the contract he would become a partner in the firm and that during the term he would be paid “like a partner.” The written agreement did not reflect this promise—the contract read that Holm would be paid based on “net collections” for his services and did not state that he would become a partner. Later, Gateway told Holm that it did not intend to make him a partner. Holm filed a complaint in an Arizona state court against Gateway, alleging breach. Before the trial, Holm filed a motion to reform the contract to express what he had been told. Nottingham did not dispute Holm’s account. What is the basis for the reformation of a contract? Is it appropriate in this case? Why or why not?

14–4. Express Warranties. Charity Bell bought a used Toyota Avalon from Awny Gobran of Gobran Auto Sales, Inc. The odometer showed that the car had been driven 147,000 miles. Bell asked whether it had been in any accidents. Gobran replied that it was in good condition. The parties signed a warranty disclaimer that the vehicle was sold “as is.” Problems with the car arose the same day as the purchase. Gobran made a few ineffectual attempts to repair it before refusing to do more. Meanwhile, Bell obtained a vehicle history report from Carfax, which showed that the Avalon had been damaged in an accident and that its last reported odometer reading was that the odometer reading could be false and that the car might have been in an accident? Can Gobran avoid any liability that might otherwise be imposed because Bell did not obtain the Carfax report until after she bought the car? Discuss.

Required information

[The following information applies to the questions displayed below.]

Susan Lopez, a consultant with Deloitte & Young, has just begun an engagement at Four Corners Airlines, which is based in Santa Fe, New Mexico. The company has fallen on hard times of late despite record profits for the rest of the airline industry. Management is somewhat set in its ways and could probably use some “new blood,” as the most recent hire to the firm’s executive team was 12 years ago.

In Lopez’s first meeting with the team, the airline’s chief executive officer commented that “all that mattered in this industry were load factors—the percentage of seats sold on scheduled flights. If load factors were adequate, everything else would take care of itself.” Lopez noted that while this measure was important, other, broader facets of operation were significant as well. She asked if any of the management team had heard of the balanced scorecard, and received dead silence as a response.

Based on her experiences with other engagements, including two that involved airlines, Lopez was convinced that the balanced scorecard could provide benefits in helping to solve the airline’s woes. After a presentation about the philosophy of the balanced scorecard, Four Corners Airlines’ management team accepted her idea, feeling that a shift in operating philosophy was needed for survival.

Personal Skill Builder 5-3: Dealing with People Who Make Your Life Difficult: Roary—the Exploder!

1. Read the following statement from B. J. Karim, an employee at Poore Brothers, a plumbing supply and distribution company:

I have a boss, Ralph Poore, who is the consummate Dr. Jekyll and Mr. Hyde. On some days, Poore can be the nicest and kindest person, but on others—that’s another story. Behind his back, we call him Roary because when he’s angry, he speaks at such a loud volume that anyone within miles can hear him. He shows his impatience and displeasure by exploding at the drop of a hat. He has meetings where, if someone disagrees with him or delivers bad news about what is happening at the company, he will pound his hands on the table and yell at the top of his lungs. More than once, Poore has ended the meeting with one of these tirades, either by kicking everyone else out or by leaving.

Once, Roary went into one of the salespeople’s offices to ask if he had called on a contractor as asked. When the salesperson answered that the person was not there when he called but that he had sent a fax and a copy of some new fixtures the company had just gotten in, Poore stormed out of the office, shouting obscenities.

When Poore hears bad news, it doesn’t matter whose fault it is—he blows up at whoever is there. Another time, Poore was speaking to another of my co-workers about a delivery she needed to arrange. She told Poore that Crane’s manufacturing facility was about three months behind in its production runs. We couldn’t deliver the product because Crane hadn’t produced it. Poore picked up a flower vase and threw it across the room.

Poore is always right—in his mind. If anyone disagrees with him or tells him something he doesn’t want to hear, he throws a tantrum. This man is a time bomb waiting for something to set him off. I haven’t felt his wrath, but it’s only a matter of time.

Analyze Roary’s leadership style. When might this style be appropriate? What might be some disadvantages of this style?

Based on your findings, what suggestions would you make to Karim on how to cope with Roary?
