In a study on coronary artery disease, the time a patient can spend on a treadmill is measured while still drinking beer and measured again after six months of having quit drinking beer. Test the hypothesis that quitting drinking beer leads to longer time in treadmill. Use 5% level of significance. 1. Generate the Null and Alternative hypothesis ( in words and in symbols)
