A research engineer for a tire manufacturer is investigating tire life for a new rubber compound and has built 16 tires and tested them to end-of-life in a road test. The sample mean and standard deviation are 60489.7 and 3645.94 kilometers. The engineer would like to demonstrate that the mean life of this new tire is in excess of 60,000 kilometers. Formulate the appropriate hypotheses. Test the appropriate hypotheses usinga : 0.05. Is it possible to reject Ho hypothesis at the 0.05 level of significance? (Assume data is normally distributed). =
