In tests of a computer component, it is found that the mean time between failures is hours. A modification is made which is supposed to increase reliability by increasing the time between failures. Tests on a sample of modified components produce a mean time between failures of hours. Using a level of significance, perform a hypothesis test to determine whether the mean time between failures for the modified components is greater than hours. Assume that the population standard deviation is hours.
