Solved: Many older homes have electrical systems that use fusesrather than circuit

Chapter 8, Problem 6

(choose chapter or problem)

Many older homes have electrical systems that use fusesrather than circuit breakers. A manufacturer of 40-ampfuses wants to make sure that the mean amperage at whichits fuses burn out is in fact 40. If the mean amperage is lowerthan 40, customers will complain because the fuses requirereplacement too often. If the mean amperage is higher than40, the manufacturer might be liable for damage to an electricalsystem due to fuse malfunction. To verify the amperageof the fuses, a sample of fuses is to be selected and inspected.If a hypothesis test were to be performed on the resultingdata, what null and alternative hypotheses would be of interestto the manufacturer? Describe type I and type II errors inthe context of this problem situation.
