Problem 1: How much time do Americans living in or near cities spend waiting in traffic, and how much does waiting in traffic cost them per year? The file Congestion includes this cost for 31 cities. (Source: Data extracted from “The high Cost of Congestion,” Time, October 17, 2011, p.18.)

2. b) Compute the range, interquartile range, variance, and standard deviation.

3. c) Compute the covariance between the time spent sitting in traffic and the cost of sitting in

   traffic.

4. d) Computethecorrelationbetweenthetimespentsittingintrafficandthecostofsittingin

   traffic.

5. e) Based on the results of (a) through (d), what conclusions might you reach concerning the

   time spent waiting in traffic and the cost of waiting in traffic?

6. f) Create a histogram for each of the two variables: the time Americans living in or near cities

   spend waiting in traffic and the cost of waiting per year.

7. g) Create a scatter plot for the two variables and fit a straight line to the points. Show the

   equation of the fitted line.

In January 2017, Mitzu Co. pays $2,600,000 for a tract of land with two buildings on it. It plans to demolish Building 1 and build a new store in its place. Building 2 will be a company office; it is appraised at $750,000, with a useful life of 20 years and a $85,000 salvage value. A lighted parking lot near Building 1 has improvements (Land Improvements 1) valued at $360,000 that are expected to last another 12 years with no salvage value. Without the buildings and improvements, the tract of land is valued at $1,890,000. The company also incurs the following additional costs:

Cost to demolish Building 1 $ 339,400
Cost of additional land grading 191,400
Cost to construct new building (Building 3), having a useful life of 25 years and a $400,000 salvage value 2,302,000
Cost of new land improvements (Land Improvements 2) near Building 2 having a 20-year useful life and no salvage value 168,000

Allocate the costs incurred by Mitzu to the appropriate columns and total each column.

2. Prepare a single journal entry to record all the incurred costs assuming they are paid in cash on January 1, 2017.

3. Using the straight-line method, prepare the December 31 adjusting entries to record depreciation for the 12 months of 2017 when these assets were in use.

CASE STUDY: The Nepalese Himalayas, A Protected Ecosystem?

In May of 2007 some 43 expeditions totalling 470 climbers summitted Mount Everest from both the Nepalese and Tibetan sides of the mountain. At one stage over 60 climbers were on or near the summit waiting (in some cases up to 1–2 hours) in order to get their chance to stand on the highest point in the world. If those 470 climbers had been asked why they chose to climb Mt Everest, somewhere in their answers would have been sentiments expressing a desire to experience one of the wildest places on earth. Technological innovations in mountaineering equipment, such as advanced clothing, bottled oxygen and the growth in the popularity of commercialized expeditions where clients are charged between US$40,000 and US$50,000 to be guided up the mountain will continue to attract hundreds of climbers as they attempt to fulfill a desire to experience one of the wildest places on earth. Research carried out in Sagarmatha (Mt Everest) National Park indicates that ecosystems above 4000 metres have been significantly impacted by tourism in the past 30 years. Impacts include the overharvesting of fragile alpine shrubs and plants for expedition and tourist lodge fuel, overgrazing, accelerated erosion, and uncontrolled lodge building. The present Nepalese government will continue to encourage tourism, as it is the country’s highest income earner.

YOUR ARGUMENT FOR OR AGAINST: A drastic reduction in expedition numbers and call for the complete banning, for 1 year, of climbing on all peaks over 8000 metres high. This reduction is necessary in trying to mediate a compromise between the conflicting needs of access, availability and presentability of an environmental or ecological product – wilderness – with those of the local population and the regenerative capacity of the ecosystem.

SUPPORT YOUR ARGUMENT WITH FACTS.

PARASITOLOGY QUESTION:

Amoeba case study

Calatagan is a third-class municipality in the province of Batangas, Philippines. It has a total population of 30,500 with a total of 8 barangays. The municipality’s major revenue comes from agriculture and aquaculture. A section of the population is employed in “Ang Pulo,” an island housing a mangrove forest conservation park located in the northeast. Some residents of Calatagan are settled along the major highway that connects it to neighboring municipalities, while some live further inland, usually near farms. Major streets are cemented but small streets are not. Deep well is the main source of water but there is one water distillery station serving three barangays in the municipality. In the summer of 2005, there were 950 cases of a rare eye infection in one barangay that affected residents of different ages. The infection is characterized by severe pain and reddening of the cornea. Antiviral drugs where administered but the patients’ condition did not improve. There were also 1500 reported cases of diarrhea by the RHU. Stool examination results from specimens submitted by patients revealed an increase in WBC count. Strange crystal-like structures were also seen under the microscope in some of the stool specimens. The mayor of Calatagan ordered an immediate investigation of the probable cause of the cases.

Questions to answer:

1. Identify the probable cause of the incidents in Calatagan, Batangas. Justify. (provide references for your answers)

2. What could have been the sources of infection of the residents in Calatagan? Describe the probable mode of infection for each identified cause. Cite examples and references.

3. Briefly provide a possible plan of action on how to control the cases in Calatagan.

enny, Inc., is looking at setting up a new manufacturing plant in South Park. The company bought some land six years ago for $8.1 million in anticipation of using it as a warehouse and distribution site, but the company has since decided to rent facilities elsewhere. The land would net $10.9 million if it were sold today. The company now wants to build its new manufacturing plant on this land; the plant will cost $22.1 million to build, and the site requires $960,000 worth of grading before it is suitable for construction.

What is the proper cash flow amount to use as the initial investment in fixed assets when evaluating this project? (Do not round intermediate calculations and enter your answer in dollars, not millions, rounded to the nearest whole number, e.g., 1,234,567.)

Parker & Stone, Inc., is looking at setting up a new manufacturing plant in South Park to produce garden tools. The company bought some land six years ago for $5.1 million in anticipation of using it as a warehouse and distribution site, but the company has since decided to rent these facilities from a competitor instead. If the land were sold today, the company would net $5.4 million. The company wants to build its new manufacturing plant on this land; the plant will cost $12.6 million to build, and the site requires $780,000 worth of grading before it is suitable for construction.
