u are considering upgrading some manufacturing facilities by purchasing one of the three different machines, each with the same production capacity. Machine A costs $30,000, has a life of 40 years, annual maintenance costs of $1500 and a salvage value of $5000. Machine B costs $20,000, has a life of 20 years, annual maintenance of $2000 and a salvage value of $3000. Machine C costs $10,000 has a life of 10 years, annual maintenance of $4000 and no salvage value. Determine the most economical choice based on minimizing the present value of total costs. Use an annual discount rate of 10%. Assume that initial costs, annual maintenance and discount rates are constant throughout the analysis period

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.
