scenario：You have been asked to serve on a committee that advises the World Bank about how to fund a healthcare system in the developing world. As part of this role you need to design a healthcare system for the country described below costing no more than $500 million that keeps the largest possible number of people healthy:
This country is about the size of Texas—250,000 square miles. A mountain range separates the country into two regions.
Ten million people live in the coastal region, while five million live in the inland region.
Half the people live in urban areas, and the other half are evenly distributed through the country.
The coastal region has a hot, moist, tropical climate that supports lush jungles and fertile farmland.
The inland region is dry and cool and is predominantly grassland and forest.
The coastal region is well serviced by roads, but only about half the people in the inland region have convenient access to roads.
Only the largest cities and towns have modern sanitation.
Malnutrition and malaria are problems, few people are vaccinated, and there is little health care currently available.
Most people grow their own food and have little extra money to spend. Few children attend school.
Challenge: Think of health care options for this country in terms of:
1. What are some options which should be included?
2. What are some options which should not be included ?

"A contributing factor to an airplane's duel consumption is the bypass ratio of the engine system. The bypass ratio is the amount of air passing around the engine core relative to the amount of air passing through the core. An airplane manufacturer is designing a new airplane and wants to determine the bypass ratio for the airplane's engine system. The airplane will fly 4,100 hours per year and will average 480 miles per hour. The amount of fuel that the airplane consumes can be expressed as:
z = 0.0497 - (7.92*10^-4) * y
for 4 < y < 12
where y is the bypass ratio (a unitless number) and z is the number of gallons of fuel consumed per mile flown by the airplane. The cost of fuel remains constant at $4.29 per gallon.
The initial cost of the engine system as a function of the bypass ratio is $312,000 + $2,800y^2.
The engine system will be used for 9 years. At the end of 9 years, the salvage value of the engine system as a function of bypass ratio is $10,000y. The airplane manufacturer wants to minimize the annual equivalent cost (AEC) of the engine system (which includes the initial cost, the annual cost of fuel, and the salvage value). The manufacturer's MARR is 13.9%. What is the optimal bypass ratio rounded to the nearest tenth that minimizes the AEC of the engine system?
(The optimal answer for the bypass ratio is between 4 to 12, but it should not be necessary to consider that constraint in your calculations.)"

Natalie is also thinking of buying a van that will be used only for business. The cost of the van is estimated at $38,500. Natalie would spend an additional $2,500 to have the van painted. In addition, she wants the back seat of the van removed so that she will have lots of room to transport her mixer inventory as well as her baking supplies. The cost of taking out the back seat and installing shelving units is estimated at $1,500. She expects the van to last her about 5 years, and she expects to drive it for 100,000 miles. The annual cost of vehicle insurance will be $2,400. Natalie estimates that at the end of the 5-year useful life the van will sell for $6,500. Assume that she will buy the van on August 15, 2018, and it will be ready for use on September 1, 2018. Natalie is concerned about the impact of the van’s cost on her income statement and balance sheet. She has come to you for advice on calculating the van’s depreciation. Instructions:

(a) Determine the cost of the van.

(b) Prepare a depreciation table for straight-line depreciation (similar to the one in Illustration 9-9). Recall that Cookie Creations has a December 31 fiscal year-end.

(c) What method should Natalie use for tax purposes? Provide a justification for your choice. Is she required to use the same approach for financial reporting and tax reporting?

In its Fuel Economy Guide for 2008 model vehicles, the Environmental Protection Agency gives data on 1152 vehicles. There are a number of outliers, mainly vehicles with very poor gas mileage. If we ignore the outliers, however, the combined city and highway gas mileage of the other 1120 or so vehicles is approximately Normal with mean 18.7 miles per gallon (mpg) and standard deviation 4.3 mpg. The 2008 Chevrolet Malibu with a four-cylinder engine has combined gas mileage 25 mpg. What percent of all vehicles have worse gas mileage than the Malibu? % How high must a 2008 vehicle's gas mileage be in order to fall in the top 10% of all vehicles? (The distribution omits a few high outliers, mainly hybrid gas-electric vehicles.) The quartiles of any distribution are the values with cumulative proportions 0.25 and 0.75. They span the middle half of the distribution. What are the quartiles of the distribution of gas mileage? Gas mileage of the first quartile: Gas mileage of the third quartile: The quintiles of any distribution are the values with cumulative proportions 0.20, 0.40, 0.60, and 0.80. What are the quintiles of the distribution of gas mileage? Gas mileage of 0.20 of the distribution: Gas mileage of 0.40 of the distribution: Gas mileage of 0.60 of the distribution: Gas mileage of 0.80 of the distribution:

Exercise 14-9 Algo

A realtor studies the relationship between the size of a house (in square feet) and the property taxes (in $) owed by the owner. The table below shows a portion of the data for 20 homes in a suburb 60 miles outside of New York City. [You may find it useful to reference the t table.]

a-1. Calculate the sample correlation coefficient r_xy. (Round intermediate calculations to at least 4 decimal places and final answers to 4 decimal places.)

Imagine that Mark contracts with the fictional J.B. Used Cars to purchase a used 2009 red, automatic Toyota Camry for $14,988 through a special two-day sale. Mark pays in full for the car and is told that the car lot will deliver the Camry to Mark's house free of charge as soon as the transfer of title is cleared. However, the seller begins making excuses and fails to ever deliver the car. Thus, the seller is in breach of contract because Mark already paid for the Camry and never received his vehicle. Mark needs a new car soon, so he decides to obtain cover instead of cancelling the contract with the seller. He searches at other local car dealers and, two days after finding J.B. Used Cars in breach of contract, he finds another Camry that he is satisfied with. It is a 2009 silver Camry that costs $17,982; it is an automatic, and it has roughly the same number of miles as the Camry from J.B. Used Cars. This price is comparable to the standard Blue Book price for a 2009 Camry.

1. What does it mean to obtain cover after a seller breaches a contract? Why does the buyer in this situation obtain cover?

2. What are the four criteria that a buyer must meet to obtain cover? In this case, do Mark's actions appear to meet those criteria?

3. What is the formula used to determine damages in cover cases? How much in damages would Mark be awarded by the courts in this situation?

2. The following data was gathered by Taxon Auto to model the relationship between automobile weight and miles per gallon.

a. Which variable is the dependent or response variable?

b. Which is the independent or explanatory variable?

Enter the data into an Excel spreadsheet.

c. Create a scatterplot

i. Interpret your scatterplot

ii. Based on the scatterplot - does it appear that linear regression would be a useful tool for prediction of ridership?

Regardless of your answer to c. Run the regression analysis in Excel and use the output to answer the following questions:

d. What is the value of the correlation coefficient? How would you interpret it?

e. What is the value of the coefficient of determination? How would you interpret it?

f. Write the hypotheses for the test of the slope.

g. What is the p-value for the test of the slope? What is your conclusion based on this result?

h. What is the regression formula the represents the relationship between auto weight and MPG?

i. Use your formula to predict the MPG for a car that weighs 3500 pounds. (show formula)

j. Use your formula to predict the MPG for a car that weighs 2100 pounds. (show formula)
