A company has 3 machines: A, B, and C. The number of breakdowns
per week is distributed Poisson. On average, machine A breaks down
.4 times per week, machine B breaks down .45 times per week and
machine C breaks down .9 times per week. The probability that there
are 2 breakdowns in one week is _____ (round to 4 decimal
places).

The Local Bottling Company has just installed a new bottling
process that will fill 16-ounce bottles of the popular Paradise
Classic Cola soft drink. Both overfilling and underfilling bottles
are undesirable: Underfilling leads to customer complaints and
overfilling costs the company considerable money. In order to
verify that the filler is set up correctly, the company wishes to
see whether the mean bottle fill, μ, is close to the
target fill of 16 ounces. To this end, a random sample...

Caine Bottling Corporation is considering the purchase of a new
bottling machine. The machine would cost $228,168 and has an
estimated useful life of 8 years with zero salvage value.
Management estimates that the new bottling machine will provide net
annual cash flows of $33,500. Management also believes that the new
bottling machine will save the company money because it is expected
to be more reliable than other machines, and thus will reduce
downtime. Assume a discount rate of 5%....

The Lubbock County Bureau of Weights and Measures received
complaints that a local bottling company was putting
less than 20 ounces of root beer in its bottles (labeled 20 oz.). A
random sample of fourteen 20-oz. bottles will be
randomly selected and its contents will be measured to test the
claim that the bottling company is putting significantly
