Scientists at the University of Massachusetts at Amherst have used a bacterial organism, known as Geobacter species, in a fuel cell to generate electricity. Describe, in detail, the principle and process of electrical energy generation from bacterial fuel cell. Also include in the discussion major advantages and limitations of bacterial fuel cells.

For 40 days in the summer, you are working in a small, student-run company that sends out merchandise with university branding to alumni around the world. Every day, you take a sample of 50 shipments that are ready to be shipped to the alumni and inspect them for correctness. Across all days, the average percentage of incorrect shipments is 5 percent. What would be the center line for a p-chart?

40

50

0.05

2.5

None of the above

1. We try to study the relationship between a personality scale that measures willingness to take orders (on a scale from 0 to 20, where 20 represents eagerness to take orders) and the number of days served in county prison for misdemeanors. Here are the data from a sample of six prisoners:

Mean of the Willingness score tells us:

Median of the Days Served tells us:

Variance of the willingness score tell us:

Standard Deviation of the days served tells us:

While try to find the relationship of these two variables,

Which one is the dependent variable?

Which one is the independent variable?

What is the Sample Covariance?

What is the sample coefficient of correlation (r) and what does this tell us?

What is the Coefficient of Determination (R²) and what is this telling us?

What is the Slope coefficient (b₁) and what is this telling us?

What is the y-intercept (b₀) and what is this telling us?

From the above measures, particularly your r and R², can you say that the low scores of the willingness will cause the prisoner serving more days in Jail? Why or why not?

Assume the US market of sunflower oil was described by the following domestic supply and demand equations:

QDUS = 8000 – 4 P

QSUS = -2000 + 6 P

where QDUS and QSUS represent the quantities demanded and supplied (in tons) and P is the price per ton of sunflower oil (in $).

4) Now add this information:

In 2008, China entered into the World Trade Organization and became the largest importer of US sunflower oil. Assume the Chinese import demand for sunflower oil from the US in 2008 was

QDCHINA = 20000 – 10 P

1) What was the market (equilibrium) price of sunflower oil?

2) Using your work in question 1, what was the market (equilibrium) quantity of sunflower oil?

3) Using your work in questions 1 and 2, what were revenues for the suppliers of sunflower oil?

4) Given this information, what was the new equilibrium price of sunflower oil in 2008? (Hint: what is the total demand for US sunflower oil?)

5) Given the price you calculated in the previous question, what was the equilibrium total quantity demanded?

6) Given your answers in the previous 2 questions, how much of the new equilibrium quantity was consumed in the US (i.e., US quantity demanded given the new equilibrium price)?

7) Given your answers in the previous three questions, how much sunflower oil did China purchase from US producers? (i.e., China quantity demanded)

8) Given your calculations in questions # 4 and #5, what were US sunflower oil producer revenues?

Match each scenario with the SINGLE MOST appropriate test. Each answer choice may be used once, more than once, or not at all. Assume all data collection is by random sampling unless the question suggests otherwise.

Outback Outfitters is a manufacturer of recreational equipment. It has been experiencing an average growth rate of 20% in sales over the past 5 years. It is August 31 and the financial controller has just prepared the company’s budgeted income statement for next year. The company has no sales force of its own and outsourcing its selling and marketing functions to an independent sales agents. The commission paid to the agent is 12% on sales for all the different products the company sold. The statement follows:

When the financial controller handed the statement to the CEO, the CEO informed the controller that the sales agent demanded an increase in the commission rate to 16% next year to cover the increasing expenses in marketing and selling the products of Outback Outfitters.

The CEO concerns that the sales agent might ask for further increase in the commission rate in the future and would like to set up its own sales team. He asks the help of the financial controller and he gathers the following information for setting up the sales team:

Commission rate to own sales team 8%

Required:

a. Prepare a contribution margin income statement for next year at the 16% commission rate.

b. Calculate the contribution margin ratio and break-even in dollar sales for next year assuming:

(1) Commission rate remains at 12%.

(2) Commission rate is increased to 16%.

c. Determine the volume of sales under 16% commission rate that would be required to generate the same net operating income under the 12% commission rate. Compute the margin of safety percentage under 16% commission rate.

d. Calculate the contribution margin ratio, break-even dollar sales and margin of safety if the company employs its own sales team.

e. Determine the volume of sales at which the net operating income would be equal regardless of whether the company sells through agents at 16% commission rate or employs its own sales team.

f. What is meant by the term operating leverage? Calculate the degree of operating leverage that the company would expect to have for next year assuming the company (1) sells through agents at 16% commission rate and (2) employs its own sales team.

g. Based on the data in (a) through (f) above, make a recommendation as to whether the company should continue to use sales agent (at 16% commission rate) or employ its own sales team. Give reasons for your answer.
