A city's status and living conditions may affect how its residents perceive their mayor and city council. Dr. Benevita has used data from Statistics Canada to rank larger metropolitan areas against each other. Focusing on unemployment rates, median household income, and crime rates, he has given Calgary an overall positive ranking (low unemployment, high income, and relatively low crime), and Winnipeg an overall negative one (mid-range unemployment, fairly low income, and very high crime). Dr. Benevita has contacted 40 residents of each city to respond to one simple question: "How competent do you believe your municipal leaders are in governing your city?" Participants rated their municipal government on a scale of -3 (completely incompetent) to 3 (completely competent). A perfectly normal distribution around the central, neutral, point would have a mean of 0 and a standard deviation of 1.66. We will use this as our comparison point to determine whether residents of Calgary and Winnipeg have an overall positive or negative view of their municipal government
