Question
For the given hypothesis test, explain the meaning of a Type I error or a Type Il error, as specified.
In the past, the mean battery life for a certain type of flashlight battery has been 12.9 hours. The manufacturer has introduced a change in the production method and wants to perform a hypothesis test to determine whether the mean battery life
has increased as a result. The hypotheses are:
Ho: H= 12.9 hours
H:u> 12.9 hours
Explain the result of a Type l error.
O A. The manufacturer will decide the mean battery life is 12.9 hours when in fact it is greater than 12.9 hours.
O B. The manufacturer will decide the mean battery life is greater than 12.9 hours when in fact it is 12.9 hours.
OC. The manufacturer will decide the mean battery life is greater than 12.9 hours when in fact it is less than 12.9 hours.
O D. The manufacturer will decide the mean battery life is less than 12.9 hours when in fact it is greater than 12.9 hours.
O E. The manufacturer will decide the mean battery life is greater than 12.9 hours when
fact it is greater than 12.9 hours.
