Margin of error A medical researcher estimates the percentage of children exposed to lead-based paint, adding that he believes his estimate has a margin of error of about 3%. Explain what the margin of error means.

Urban Economics 8
Paris versus Detroit Suppose the benefi t and cost curves of the high-income households shown in Figure 7A2 are relevant for Detroit. In contrast, high-income households in Paris take 50 percent more trips to the city center (for work and cultural opportunities). While Detroiters commute in air-condi
