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 W39} and 3645.94 kilometers. The engineer would like to demonstrate that the mean life of this new tire is in exeess of 611111)!) kilometers. Formulate the appropriate hypotheses. Test the appropriate hypotheses usingrt = (1.115. Is it possible to reject H\" hypothesis at the (1115 level of signicance
