Two incinerators are being considered by a waste management company. Design A has an initial cost of $2,950,000, has annual operating and maintenance costs of $650,000, and requires overhauls every 5 years at a cost of $950,000. Design B is more sophisticated, including computer controls; it has an initial cost of $5,950,000, has annual operating and maintenance costs of $700,000, and requires overhauls every 10 years at a cost of $3,400,000. Using a 9.5 %/year interest rate, determine the capitalized cost for each design and recommend which design should be chosen

a.
Design A= $13,605,253
Design B= $14,786,379
Design A is preferred over B

b.
Design A= $14,605,253
Design B= $15,786,379
Design A is preferred over B

c.
Design A= $14,605,253
Design B= $13,786,379
Design B is preferred over A

d.
Design A= $16,305,253
Design B=$17,486,379
Design A is preferred over B .

Acompany is developing a new high­performance wax for cross country ski racing. in order to justify the price marketingwants, the wax needs to be very fast. specifically, the mean time to finish their standard test course should be less thanseconds for a former olympic champion. to test it, the champion will ski the course 8 times. the champion's times(selected at random) are 59.9 61.9 48.8 52.2 46.6 45.3 50.6 and 41.1 seconds to complete the test course. complete parts a and b below. a) should they market the wax? assume the assumptions and conditions for appropriate hypothesis testing are metfor the sample. assume=0.05. what are the null and alternative hypotheses? choose the correct answer below. b) suppose they decide not to market the wax after the test, but it turns out that the wax really does lower the champion'saverage time to less thanseconds. what kind of error have they made? explain the impact to the company of such anerror.

Post test question number 9 for entering the job market

The owner of firewood to go is considering buying a hydraulic wood splitter which sells for $50,000. he figures it will cost an additional $100 per cord to purchase and split wood with this machine, while he can sell each cord of split wood for $125. if, for this machine, design capacity is 50 cords per day, effective capacity is 40 cords per day, and actual output is expected to be 32 cords per day, what would be its efficiency?
