A research engineer for a tire manufacturer is investigating tire life for a new rubber compound. She has built n = 10 tires and tested them to end-of-life in a road test. The sample mean and standard deviation are x = 63245 and s = 3035 kilometers, respectively. Assume that lifetimes of tires created from the new compound are distributed Normal with mean mu . Test H_0: mu = 61000 against H_a: mu > 61000 at alpha = 0.05. Give the rejection region. Compute a 95% confidence lower bound for mu . Use the bound found in part (b) to test the hypotheses given in part (a). (You should have the same conclusion as in (a), but this time justify your answer based only on the confidence lower bound.)
