question 97

Multiple Choice

Angela Chou has been asked to investigate the determinants of poverty in Ontario communities. She collected data on 60 communities from Statistics Canada. She selected the percentage of poor persons living under the poverty line [Poor (%) ], measured by Low Income Cut-Off, designed by Statistics Canada as a measure of poverty for a community, as the dependent variable. The independent variables selected are percent of single families in each community, the unemployment rate in each community, and percent of population in the community holding a bachelor's degree as their highest level of education attained. Determine the regression equation.

• A) Poor (%) = -3.81 + 0.798 Single-Families (%) + 0.624 Unemployment Rate (%) - 0.170 Bachelor's Degree (%)
• B) Poor (%) = -3.88 + 0.798 Single-Families (%) + 0.625 Unemployment Rate (%) - 0.170 Bachelor's Degree (%)
• C) Poor (%) = 3.88 + 0.798 Single-Families (%) + 0.625 Unemployment Rate (%) - 0.170 Bachelor's Degree (%)
• D) Poor (%) = -3.88 - 0.798 Single-Families (%) - 0.625 Unemployment Rate (%) - 0.170 Bachelor's Degree (%)
• E) Poor (%) = 3.88 + 0.798 Single-Families (%) + 0.625 Unemployment Rate (%) + 0.170 Bachelor's Degree (%)
