Part A Harley Davidson has its engine assembly plant in
Milwaukee and its motorcycle assembly plant in Pennsylvania. Both
plants run 365 days a year. Engines are transported from the
Milwaukee plant to the Pennsylvania plant using trucks. Each truck
trip costs $1,500. The motorcycle plant assembles and sells 300
motorcycles each day. Each engine costs $450 and Harley incurs a
holding cost of 20 percent per year. How many engines should Harley
load onto each truck? What is the...

1. Murphy’s Law, a pub in downtown Rochester, claims its patrons
average 25 years of age. A random sample of 40 bar patrons is taken
and their mean age is found to be 26.6 years with a standard
deviation of 4.5 years. Do we have enough evidence to conclude at
the level of significance α = 0.025 that, on average, patrons at
Murphy’s Law are older than 25?

17. A tire manufacturer claims that the average life of a
certain grade of tire is 50,000 miles or more when used under
normal driving conditions. A random sample of 20 tires is selected
and tested and the sample mean is 49,650 miles. Assume the
population of the lives is to be normal with standard deviation of
5,000 miles. At the 5% significance level, the manufacturer’s claim
is tested. What is the decision rule in this test?
A. Reject H0...

An assembly plant orders a large shipment of electronic circuits
each month. The supplier claims that the population proportion of
defective circuits is ρ=0.04. When a shipment arrives, the plant
manager selects a random sample of 300 circuits that are tested and
the sample proportion of defective circuits is computed. This
result is used for a hypothesis test to determine if there is
sufficient evidence to conclude that the population proportion of
defectives circuits from this supplier is greater than...
