hypotheses

6. Many older homes have electrical systems that use fuses rather than circuit breakers. A manufacturer of 40-amp fuses wants to make sure that the mean am- perage at which its fuses burn out is in fact 40. If the mean amperage is lower than 40, customers will complain because the fuses require replacement too often. If the mean amperage is higher than 40, the manufacturer might be liable for damage to an elec- trical system due to fuse malfunction. To verify the amperage of the fuses, a sample of fuses is to be se- lected and inspected. If a hypothesis test were to be performed on the resulting data, what null and alter- native hypotheses would be of interest to the manu- facturer? Describe type I and type II errors in the context of this problem situation.
