Assume that a simple random sample has been selected from a normally distributed population and test the given claim. Use either the traditional method or P-value(or range of P-values) as appropriate, and state the final conclusion that address the original claim. 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. Tests on a random sample of 10 modified components resulted in the following time(in hours) between failures. 518 548 561 523 536 499 538 557 528 563 At the 0.05 significance level, test the claim that for the modified components, the mean time between failures is greater than 520 hours. Use the P-values method of testing hypotheses.
