Many people suffer from heartburn. It appears, however, that the problem may increase with age. A researcher for a pharmaceutical company wanted to determine whether age and the incidence and extent of heartburn are related. A random sample of 325 adults was drawn. Each person was asked to give his or her age and to rate the severity of heartburn (1 = Low, 2 = Moderate, 3 = High, 4 = Very high). Do these data provide sufficient evidence to indicate that older people suffer more severe heartburn?
