Question: In tests of a computer component, it is found that the mean time between failures is 520 hours. A modification is made which is supposed to increase the time between failures. Test on a random sample of 35 components resulted in the following time (in hours) between failures. At the 0.05 significance level, test the claim that for the modified components, the mean time between failures is greater than 520 hours.
