Using the strategy that you developed in SLP3, run the simulation. Document your results as you did previously. Review and analyze these results, and develop a final strategy.

Please turn in a 6- to 8-page paper, not including cover and reference pages.

Keys to the Assignment

The key aspects of this assignment that should be covered and taken into account in preparing your paper include:

• The revised strategy consists of the Prices, R&D Allocation %, and any product discontinuations for the X5, X6, and X7 tablets for each of the four years: 2012, 2013, 2014, and 2015.
• You must present a rational justification for this strategy. In other words, you must provide support for your proposed strategy using financial analysis and relevant theories.
• Use the CVP Calculator and review the PowerPoint that explains CVP and provides some examples.
• You will need to crunch some numbers (CVP Analysis) to help you determine your prices and R&D allocations.
• Make sure your proposed changes in strategy are firmly based in this analysis of financial and market data and sound business principles. Your goal is to practice using CVP and get better at it.
• Present your analysis professionally, making strategic use of tables, charts, and graphs.

Expansion Plans for Scooter Land

Scooter Land had been headquartered and doing business solely in the United States for five years.  They had an excellent reputation for a quality product and demand was at an all-time high. The CEO of the company decided to explore the possibility of expanding into two or three foreign countries. Each foreign facility would include operations, distribution, and sales of the scooters.

 

The CEO assigned John, the Director of Operations, to be in charge of performing the preliminary work in making the decisions regarding the expansion into other countries. John started by visiting Central America and Africa because of the reported low cost of doing business in these areas. After his visits, however, John rejected these countries because of the dangerous business climates and insufficient disposable income in their marketplaces.

 

John also performed a detailed analysis of 75 additional countries, hiring an expensive consultant to assist him with the analysis of the extensive amount of information obtained. By the time that John and the consultant finished their analysis, six months had passed and they had spent more than $100,000.

 

Before completely giving up on the project, the CEO asks you to provide input to John. He feels that the project can be saved if John heads in the right direction. He asks you to first describe five (5) external sources of information that John should have used to collect country information for analysis purposes.  Because you oversee operations, he also asks you to identify and discuss three (3) control instruments that the business might use to govern the international operations.  This is critical to know if the company moves forward with the expansion.

 

Spencer and Frank's Faux Pas

 

Aluminum Fencing Company (AFC) was a sizeable distributor of chain-link fencing for commercial and residential use. The company had four regional locations in the United States. Each location included a large warehouse facility for storing the chain link parts needed to assemble the fencing.  At every location there was a president; a director of workplace security; and various vice presidents, senior managers, and managers in charge of shipping and receiving, training, computer service and maintenance, accounts payable and receivable, advertising, marketing, customer service, and sales.

 

Spencer and Frank were employed at the southern-region facility. They were both hourly employees, with no employment contract.  Spencer was an accounts payable associate, and Frank was a clerk in the shipping and receiving department. Both were part of a labor union and were covered by a collective bargaining agreement. Although the men worked at completely different locations within the facility – at opposite ends of the physical plant – they initially met at a division meeting. Then one day, shortly after they had met, the two happened to run into each other at a local restaurant on their lunch breaks.

 

After that time, Spencer and Frank kept in contact in an extremely discreet manner and began seeing each other after working hours. The majority of the time, they met at one or the other's residence. When they did go out, it was after dark, in a part of town that was at least 30 miles away from the AFC facility. Their relationship began to get serious, but they still did not indicate to others that they were more than casual acquaintances through their employment with AFC.

 

One day, Spencer and Frank arranged to bring their lunches and meet at lunchtime. Their meeting place was a deserted storage room, used to house sensitive company computer software. Because Frank knew there was a lock on the door and no one ever used that storage room, Spencer and Frank felt safe to meet there unnoticed.  They decided, in advance, to take different routes to the storage room and to arrive and depart at separate times.

 

After they finished with their lunches, one thing led to another and they engaged in a sexual liaison. Since they had taken strict precautions to ensure that they would not be seen together, they did not worry that their sexual relationship in general or their sexual encounter in the storage room would be discovered. What they did not realize was that there were hidden security cameras in every room that housed sensitive data, machinery, or equipment, and the room in which they met still had a surveillance camera behind one of the walls.

 

The director of workplace security brought the fact that a camera had captured

Spencer and Frank in a compromising position to the attention of both Spencer's and

Frank's managers. Both employees were fired and then decided to bring suit against AFC based on sexual discrimination.

 

 

 

Answer the following questions related to this case:

 

1. Did AFC have the right to fire Frank and Spenser over something they did in a very discreet manner during their lunch break?

 

2. Do Frank and Spencer have a legitimate lawsuit based upon sexual discrimination?

 

3. Is there an issue with employment-at-will? 

 

4. Is there a right to privacy issue? 

 

5. Using deontological, utilitarian and virtue ethics as your guides, define each of these three ethical theories and discuss how you believe the company would act based upon each of these three ethical viewpoints.

Question 16        5 / 5 points
A large test statistic F tells us that the sample means _______ the data within the individual samples, which would be unlikely if the populations means really were equal (as the null hypothesis claims).
Question options:

a)     differ more than


b)     differ less than


c)     are equal to


d)     don't vary with

Question 17        5 / 5 points
The margin of error in estimating the population mean of a normal population is E = 9.3 when the sample size is 15. If the sample size had been 18 and the sample standard deviation didn't change, would the margin of error be larger or smaller than 9.3? Explain your answer.
Question options:

a)     Smaller. E decreases as the square root of the sample size gets larger.


b)     Smaller. E increases as the square root of the sample size gets larger.


c)     Larger. E decreases as the square root of the sample size gets larger.


d)     Larger. E increases as the square root of the sample size gets larger.

Question 18        0 / 5 points
Data from 8 robot swings of a 7-iron at 90 miles per hour resulted in a sample mean of 163.2 yards with a sample standard deviation of 5.8 yards. Assuming normality, carry out a hypothesis test at the 0.05 significance level to determine whether the ball meets the golfer's required average of more than 160 yards per swing.  Use the partial t-table below to solve this problem.
 
     Area in one tail
     0.025    0.05
     Area in two tails
Degrees ofFreedom    n - 1    0.05    0.10
     6    2.447    1.943
     7    2.365    1.895
     8    2.306    1.860
     9    2.262    1.833
    10    2.228    1.812
    11    2.201    1.796
    12    2.179    1.782

 
Question options:

a)     Don't reject the null hypothesis. The data don't provide sufficient evidence that the average distance is greater than 160 yards.


b)     Reject the null hypothesis. The data does provide sufficient evidence that the average distance is greater than 160 yards.


c)     t = 1.2334; Critical value = 1.992


d)     There's insufficient information to answer this question.

Question 19        5 / 5 points
One hundred people are selected at random and tested for colorblindness to determine whether gender and colorblindness are independent. The following counts were observed.
 
     Colorblind    Not Colorblind    Total
Male    7    53     60
Female    1    39     40
Total    8    92    100

 
If gender and colorblindness are independent, find the expected values corresponding to the male combinations of gender and colorblindness.
Question options:

a)     Colorblind Male 4.8; Not Colorblind Male 55.2


b)     Colorblind Male 6.8; Not Colorblind Male 53.2


c)     Colorblind Male 4.8; Not Colorblind Male 55.4


d)     Colorblind Male 4.8; Not Colorblind Male 56.2

Question 20        5 / 5 points
Which of the following statements is true?
Question options:

a)     The t distribution can be used when finding a confidence interval for the population mean whenever the sample size is small.


b)     The p distribution can be used when finding a confidence interval for the population mean whenever the sample size is small.


c)     The t distribution can't be used when finding a confidence interval for the population mean whenever the sample size is small.


d)     The p distribution can't be used when finding a confidence interval for the sample mean whenever the sample size is small.
