You wonder if there is a linear relationship between how many years someone have smoked and how hard it is to quit. You measure the number of years smoked and how hard people rated it was to quit smoking on a scale of 1-100 for 11 people. HARD = Rating of how hard it was to quit, YEARS = number of years smoked prior to quitting.
