The National Football League (NFL) records a variety of performance data for individuals and teams. To investigate the importance of passing on the percentage of games won by a team, the following data show the average number of passing yards per attempt (Yards/Attempt) and the percentage of games won (WinPct) for a random sample of 10 NFL teams for the 2011 season.†

(a)

Develop a scatter diagram with the number of passing yards per attempt on the horizontal axis and the percentage of games won on the vertical axis.

A scatter diagram has 10 points plotted on it. The horizontal axis ranges from 5 to 9 and is labeled: Yards/Attempt. The vertical axis ranges from 0 to 90 and is labeled: Win %. The points appear to be distributed somewhat randomly and are between 5 to 8.5 on the horizontal axis. The 4 leftmost points are between 35 to 65 on the vertical axis and the 5 rightmost points are between 10 to 85 on the vertical axis.

A scatter diagram has 9 points plotted on it. The horizontal axis ranges from 5 to 9 and is labeled: Yards/Attempt. The vertical axis ranges from 0 to 90 and is labeled: Win %. The points appear to be distributed somewhat randomly and are between 5 to 8.5 on the horizontal axis. The 4 leftmost points are between 40 to 85 on the vertical axis and the 5 rightmost points are between 10 to 50 on the vertical axis.

A scatter diagram has 9 points plotted on it. The horizontal axis ranges from 5 to 9 and is labeled: Yards/Attempt. The vertical axis ranges from 0 to 90 and is labeled: Win %. The points are plotted from left to right in an upward, diagonal direction starting in the lower left corner of the diagram and are between 5 to 8.5 on the horizontal axis and between 10 to 85 on the vertical axis.

A scatter diagram has 9 points plotted on it. The horizontal axis ranges from 5 to 9 and is labeled: Yards/Attempt. The vertical axis ranges from 0 to 90 and is labeled: Win %. The points are plotted from left to right in an upward, diagonal direction starting in the lower left corner of the diagram and are between 5 to 8.5 on the horizontal axis and between 5 to 80 on the vertical axis.

(b)

What does the scatter diagram developed in part (a) indicate about the relationship between the two variables?

The scatter diagram indicates no noticeable linear relationship between average number of passing yards per attempt and the percentage of games won by the team.The scatter diagram indicates a negative linear relationship between average number of passing yards per attempt and the percentage of games won by the team.    The scatter diagram indicates a positive linear relationship between average number of passing yards per attempt and the percentage of games won by the team.

(c)

Develop the estimated regression equation that could be used to predict the percentage of games won given the average number of passing yards per attempt. (Round your numerical values to three decimal places.)

ŷ =

(d)

Provide an interpretation for the slope of the estimated regression equation.

The slope gives the average number of passes per attempt when the percentage of games won is 0%.The slope gives the change in the average number of passes per attempt for every one percentage point decrease in the percentage of games won.    The slope gives the percentage of games won when the average number of passes per attempt is 0.The slope gives the change in the percentage of games won for every one yard increase in the average number of passes per attempt.The slope gives the change in the average number of passes per attempt for every one percentage point increase in the percentage of games won.

(e)

For the 2011 season, suppose the average number of passing yards per attempt for a certain NFL team was 6.5. Use the estimated regression equation developed in part (c) to predict the percentage of games won by that NFL team. (Note: For the 2011 season, suppose this NFL team's record was 7 wins and 9 losses. Round your answer to the nearest integer.)

%

Compare your prediction to the actual percentage of games won by this NFL team.

The predicted value is lower than the actual value.The predicted value is identical to the actual value.    The predicted value is higher than the actual value.

Question 1 linked to 2 3 and 4of4Total

In the context of this course, you will be asked to address the issues/questions below for Marriott International, Inc. (MAR), www.marriott.com. When addressing the issues/questions, be sure to do so in the context of this course and Marriott. You have been appointed as the special assistant to the Chief Executive Officer (CEO), Arne Sorenson, who has asked you to address the following five situations:

(a) A fellow MBA alum from Lynn University, who now works in Admission at Lynn University would like to give each MBA student a benefit, which is programmed into the Lynn University ID card. This benefit would allow the student one night each month, depending on availability, for a room at the Marriott Courtyard for $40. Normally the room rate is $100 and the full cost of a night’s stay is $50. Discuss whether or not this would be feasible, i.e. Marriott is able to do this transaction without it being a donation.

(b) Marriott currently buys its ice machines from a manufacturer in China. A representative from a company in Vietnam is offering to sell them for 20% less than cost from the manufacturer in China. Discuss the issues that you would consider in deciding whether or not to accept this offer.

(c) The CEO wishes to develop an incentive plan for the hotel managers.

Before this is put into place, the CEO wishes you to make sure that budgeting

in the hotels is done correctly. He has asked you to submit a document discussing

the key points that you have learned in MBA 640. Be as thorough as possible.

(d) Marriott has only used absorption costing. The CEO has asked you

to explain the merits of using variable costing under certain circumstances.

(e) The CEO has asked you to explain how target costing/pricing would be used in

Marriott’s pricing policies.

What are thge tradeoffs associated with such a poicy? 3. Give two examples of natural monopolies. Should the government set price ceilings in natural monopoly markets? Why? 4. Monopolistic competition has some of the same characteristics as monopoly and some of the same characteristics as perfect competiton (hence the name "monopolistic competition"). List a few of these similarities. 5. Why do monopolistically competitive firms end up making zero economic profits? 6. Why does a monopolistically competitive firm choose the level of output where marginal cost equals marginal revenue? 7. Complete this statement by filling in the blanks with the words "increase" or "decrease": The entry of an additional firm in a mon. comp. market _____________ the profit per unit of output because entry _________ the price and _____________the average cost of production. 8. Consider the Utica Slappers, a hockey team that plays in an arena with 8,000 seats. The only cost associated with staging a hockey game is a fixed cost of $6,000: The team incurs this cost regardless of how many people attend a game. The demand curve for hockey tickets has a slope of $0.001 per ticket ($1 divided by 1,000 tickets): Each $1 increase in price decreases the number of tickets sold by 1,000. For example, here are some combinations of price and quantity: Price per ticket $4 $5 $6 $7......Quantity of tickets 8,000 7,000 6,000 5,000. The owner's objective is to maximize the profit per hockey game (total revenue minus the $6,000 fixed cost). a. What price will maximize profit? b. If the owner picks the price that maximizes profit, how many seats in the arena will be empty? c. Is it rational to leave some seats empty? 9. There are a wide variety of breakfast cereals on the marketin grocery stores, they usually take up an entire aisle. As a result, it is possible to purchase many cereals that are highly similar but have small distinguishing characteristics that differentiate them. a. List some cereals that are very close substitutes for one another b. What does society gain from having all of these varieties of breakfast cereal? c. What does society lose by having all of these varieties of breakfast cereal? 10. Briefly differentiate between collusion among firms in an oligopoly and an actual cartel. 11. Give a real world example of a duopoly and a cartel.

A company sells medical supplies to hospitals and healthcare facilities that are mostly located in the Michiana region. The company has 150 employees, and it is about to decide whether part of them should be encouraged to work remotely, and if so, how many employees should do that. There are many aspects to be analyzed such as productivity and collaboration, but you will focus on the costs of space and IT at the company’s main office versus the costs of working remotely.

The costs of office space include building rent and maintenance, utilities, cleaning, and insurance. The company estimates that those costs could be either one of three scenarios: (A) $60,000 per month for a building where all employees can be accommodated; (B) $50,000 per month for a building that can accommodate 100 employees; or (C) $40,000 per month for a building for 50 employees.

The main costs of IT include the lease, operation and maintenance of equipment (a desktop computer for each employee, and the office’s Wi-Fi access points, cabling, routers for the LAN/MAN) and a contract with a fixed Internet service provider. The equipment cost is $7,500 per month for scenario (A), $5,500 for (B) or $3,500 for (C). The cost with the fixed Internet service provider is (A) $5,000 per month for all employees; (B) $4,000 per month for 100 employees; or (C) $2,500 per month for 50 employees.

If some of the employees no longer work frequently at the central office, then the company can operate on a smaller office (i.e. B or C instead of A). On the other hand, the company will provide a laptop, smartphone and a cellular plan for each employee working remotely. The company already has a corporate cellular contract with Cerizon for some employees. If some employees are to work remotely, then the company will add them to the same contract. The contract includes the smartphones at no extra cost, and Cerizon charges $10 per GB for employees who use less than 5GB per month, $8 per GB for employees who use 5GB or more but less than 10GB per month, and $6 per GB for employees who use 10GB or more per month. The cost of each laptop is $1,000, which the company considers that depreciates linearly over its lifetime of 2 years.

In the Schedule of Cost of Goods Manufactured and Cost of Goods Sold, the cost of goods manufactured is computed according to which of the following equations?

Multiple Choice

Cost of goods manufactured = Total manufacturing costs + Beginning finished goods inventory – Ending finished goods inventory

Cost of goods manufactured = Total manufacturing costs + Beginning work in process inventory – Ending work in process inventory

Cost of goods manufactured = Total manufacturing costs + Ending work in process inventory – Beginning work in process inventory
