Refer to the manufacturing company you selected for the Unit 2 Discussion and explain how you would determine the company’s contribution margin and contribution margin percent. In your initial post include the following:

• Identify which specific variables should be included in the calculation.
• Illustrate your explanation by calculating the contribution margin and contribution margin percent using hypothetical values.
• Explain what your calculated results tell you about the company’s sales and cost structure

Regarding to the above question. I have already came up with hypothetical values and calculated the contribution margin and contribution margin percent, the question that I have stuck in " what your calculated results tell you about the company’s sales and cost structure"., and what is the specific variable costs?

The selected company is beverage and food manufacture which has around $ 5000,000 sale/Revenue, $3,000,000 variable costs and 200,000 fixed costs.

Thank you in advance.

Let x be a random variable that represents red blood cell (RBC) count in millions of cells per cubic millimeter of whole blood. Then x has a distribution that is approximately normal. For the population of healthy female adults, the mean of the x distribution is about 4.8 (based on information from Diagnostic Tests with Nursing Implications, Springhouse Corporation). Suppose that a female patient has taken six laboratory blood tests over the past several months and that the RBC count data sent to the patient’s doctor are 4.9, 4.2, 4.5, 4.1, 4.4, 4.3

(a) Use a calculator to verify that ?̅= 4.40 and ? = 0.28.

(b) Do the given data indicate that the population mean RBC count for this patient is lower than 4.8? Use ? = .05.

(c) Obtain a 90% confidence interval for the mean RBC count.

(d) Can you come to the same conclusion you made in (b) using the interval approach in (c).

CASE 4.1

Manchester United Soccer Club

Nicolette Larson was loading the dishwasher with her husband, Kevin, and telling him about the first meeting of the Manchester United Tournament Organizing Committee. Nicolette, a self-confessed “soccer mom,” had been elected tournament director and was responsible for organizing the club’s first summer tournament.

Manchester United Soccer Club (MUSC), located in Manchester, New Hampshire, was formed in 1992 as a way of bringing recreational players to a higher level of competition and preparing them for the State Olympic Development Program and/or high school teams. The club currently has 24 boys and girls (ranging in age from under 9 to 16) on teams affiliated with the New Hampshire Soccer Association and the Granite State Girls Soccer League. The club’s board of directors decided in the fall to sponsor a summer invitational soccer tournament to generate revenue. Given the boom in youth soccer, hosting summer tournaments has become a popular method for raising funds. MUSC teams regularly compete in three to four tournaments each summer at different locales in New England. These tournaments have been reported to generate between $50,000 and $70,000 for the host club.

MUSC needs additional revenue to refurbish and expand the number of soccer fields at the Rock Rimmon soccer complex. Funds would also be used to augment the club’s scholarship program, which provides financial aid to players who cannot afford the $450 annual club dues.

Nicolette gave her husband a blow-by-blow account of what transpired during the first tournament committee meeting that night. She started the meeting by having everyone introduce themselves and by proclaiming how excited she was that the club was going to sponsor its own tournament. She then suggested that the committee brainstorm what needed to be done to pull off the event; she would record their ideas on a flipchart.

What emerged was a free-for-all of ideas and suggestions. One member immediately stressed the importance of having qualified referees and spent several minutes describing in detail how his son’s team was robbed in a poorly officiated championship game. This was followed by other stories of injustice on the soccer field. Another member suggested that they needed to quickly contact the local colleges to see if they could use their fields. The committee spent more than 30 minutes talking about how they should screen teams and how much they should charge as an entry fee. An argument broke out over whether they should reward the winning teams in each age bracket with medals or trophies. Many members felt that medals were too cheap, while others thought the trophies would be too expensive. Someone suggested that they seek local Page 126corporate sponsors to help fund the tournament. The proposed sale of tournament T-shirts and sweatshirts was followed by a general critique of the different shirts parents had acquired at different tournaments. One member advocated that they recruit an artist he knew to develop a unique silk-screen design for the tournament. The meeting adjourned 30 minutes late with only half of the members remaining until the end. Nicolette drove home with seven sheets of ideas and a headache.

As Kevin poured a glass of water for the two aspirin Nicolette was about to take, he tried to comfort her by saying that organizing this tournament would be a big project not unlike the projects he worked on at his engineering and design firm. He offered to sit down with her the next night and help her plan the project. He suggested that the first thing they needed to do was to develop a WBS for the project.

Questions:

1. Make a list of the major deliverables for the project and use them to develop a draft of the work breakdown structure for the tournament that contains at least three levels of detail. What are the major deliverables associated with hosting an event such as a soccer tournament?

2. How would developing a WBS alleviate some of the problems that occurred during the first meeting and help Nicolette organize and plan the project?

3. Where can Nicolette find additional information to help her develop a WBS for the tournament?

4. How could Nicolette and her task force use the WBS to generate cost estimates for the tournament? Why would this be useful information?

a. Several rivers (Red Deer, Oldman, and Bow) flow eastward into the South
Saskatchewan river basin. The South Saskatchewan river flows eastward towards
the province of Saskatchewan. There is significant irrigation in southern Alberta
primarily along the Oldman and Bow rivers. Some farmers in Saskatchewan also
irrigate along segments of the South Saskatchewan river. These Saskatchewan
farmers complain that there is not enough water for their purposes.

1.What is the fundamental market failure? Explain what it is and describe a possible remedy.

b. There is significant nitrogen leaching off fields in southern Alberta. The city of
Saskatoon, Saskatchewan draws its water supply from the South Saskatchewan
river yet it incurs significant water treatment costs to make the city water safe to
drink.

2.What is the fundamental market failure? Explain how this failure occurs.
Discuss two possible remedies and explain the trade-offs of using each.
