A civil engineer claims that more than 75% of the bridges in a certain region are in need of major repairs. To test this claim, a random sample of 100 bridges is inspected, and 85 of them are found to be in need of major repairs. At a significance level of 0.05, is there enough evidence to support the engineer's claim?

The city of Papagos, Arizona, had a deteriorating bridge in need of repair on a prominent public roadway. The city posted notices seeking proposals for an artistic bridge design and reconstruction. Davidson Masonry, LLC, which was owned and managed by Carl Davidson and his wife, Marilyn Rowe, decided to submit a bid to create a decorative concrete structure that incorporated artistic metalwork. They contacted Shana Lafayette, a local sculptor who specialized in large-scale metal creations, to help them design the bridge. The city selected their bridge design and awarded them the contract for a commission of $184,000.Davidson Masonry and Lafayette then entered into an agreement to work together on the bridge project. Davidson Masonry agreed to install and pay for concrete and structural work, and Lafayette agreed to install the metalwork at her expense. They agreed that overall profits would be split, with 25 percent going to Lafayette and 75 percent going to Davidson Masonry.…
The EPA is in process of investigating a possible water contamination issue at the manufacturing facility of NW forest products. The EPA has not yet proposed a penalty assessment. Management feels the possibility of a penalty is remote but if an assessment is made an unfavorable settlement is estimated to be $25 million . Determine how the estimated cost of the settlement will affect the current financial statements.
The production manager on the Ofon Phase 2 offshore platform operated by Total S.A. must purchase specialized environmental equipment or an equivalent service. The first cost is $250,000 with an AOC of $66,000. The manager has let it be known that he does not care about the salvage value because he thinks it will make no difference in the decision-making process. His supervisor estimates the salvage might be as high as $100,000 or as low as $10,000 in 3 years, at which time the equipment will be unnecessary. Alternatively, a subcontractor can provide the service for $165,000 per year. The total offshore project MARR is 13% per year. Determine if the decision to buy the equipment is sensitive to the salvage value. The annual worth of high salvage value is $______________ 142,525 incorrect.. The annual worth of low salvage value is $_______________ 168,940 incorrect.. Decision is sensitive…
Environmental scientists David Pimentel, Rodolfo Zuniga, and Doug Morrison of Cornell University reviewed scientific estimates for the economic and ecological costs imposed by introduced and invasive species in the United States. They found that, as of 2005, approximately 50,000 species had been introduced in the United States and that these accountedfor over $120 billion in economic costs each year. These costs include direct losses and damage, as well as costs required to control the species. (The researchers did not quantify monetary estimates for losses of biodiversity, ecosystem services, and aesthetics, which they said would drive total costs several times higher.) Calculate values missing from the table to determine the number of introduced species of each type of organism and the annual cost that each imposes on our economy. Organisms that damage crop plants are the most costlyof introduced species. Weeds, pathogenic microbes, andarthropods that attack crops together account…

In desalting groundwater that contains a significant amount of sulfates, the concentrate that is generated during the desalting process can sometimes be tough on equipment, so the equipment’s useful life is uncertain. For a treatment train that has an initial cost of $90,000 and an estimated operating cost (OC) between $15,000 and $20,000 per month, use a spreadsheet to determine how many months the equipment must last to recover the investment at i = 0.5% per month at each OC value? Assume the income from the sale of calcium sulfate is $22,000 per month. (Note: Solve using increments of $1000 OC per month.)
The Environmental Protection Agency (EPA) is in the process of investigating a possible water contamination issue at the manufacturing facility of Northwest Forest Products. The EPA has not yet proposed a penalty assessment. Management feels an assessment is reasonably possible, and if an assessment is made, an unfavorable settlement is estimated between $20 and $30 million. How should Northwest Forest Products report this situation in its current financial statements?
A Veterans Administration (VA) hospital needs to decide which type of boiler fuel system will most efficiently provide the required steam energy output for heating, laundry, and sterilization purposes. The present boilers were installed in the early 1970s and are now obsolete. Much of the auxiliary equipment is also old and requires repair. Because of these general conditions, an engineering recommendation was made to replace the entire plant with a new boiler-plant building that would house modern equipment. The cost of demolishing the old boiler plant would be almost a complete loss, as the salvage value of the scrap steel and used brick is estimated to be only about $1,000. The VA hospital's engineer finally selected two alternative proposals as being worthy of more intensive analysis. The hospital's annual energy requirement, measured in termsof steam output, is approximately 145,000,000 pounds of steam. As a general rule for analysis, 1 pound of steam is approximately 1,000 BTUs,…
A consulting engineer is considering two methods for lining landfill for municipal solid waste management in Bannock County, Idaho. A geosynthetic bentonite clay liner (GCL) will cost $2.0 million to install, and if it is renovated after 4 years at a cost of $400,000, its life can be extended another 2 years. Alternatively, a high-density polyethylene (HDPE) geomembrane can be installed that will have a useful life of 12 years. At an interest rate of 6% per year, how much money can be spent on the HDPE liner for the two methods to break even?

When red light cameras are installed at high-risk intersections, rear-end collisions go up, but all other types of accidents go down, including those involving pedestrians. Analysis of traffic accidents in a northwestern city revealed that the total number of collisions at a group of selected photo-enhanced intersections decreased from 33 per month to 18. At the same time, the number of traffic tickets issued for red light violations averaged 1100 per month, at a cost to violators of $85 per citation. The cost for the contractor to install the basic camera system at the selected intersections was $750,000. For analysis purposes, use an interest rate of 0.5% per month and a 3-year study period. The cost of a collision is estimated at $41,000 and traffic ticket costs are considered as disbenefits. (a) Calculate the B/C ratio for the camera system from the perspective of the city. (b) The contractor has proposed to operate and maintain the system, plus provide collected violation data to…
A bioengineer is evaluating methods used to apply an adhesive to microporous paper tape that is commonly used after surgery. The machinery costs $200,000, has no salvage value, and the CFBT estimate is $75,000 per year for up to 10 years. The Te = 38% and i = 8% per year. The two depreciation methods to consider are: MACRS with n = 5 years and SL with n = 8 years (neglect the halfyear convention effect). For a study period of 8 years, (a) determine which depreciation method and recovery period offers the better tax advantage, and (b) demonstrate that the same total taxes are paid for MACRS and SL depreciation.
