A researcher examines the extent to which a country’s level of prosperity can explain a country’s strength of religiosity. “Wealth” (X) of a country is measured by the Human Development Index (HDI), and “Religiosity” (Y) was measured using a scale from 0 (not religious) to 10 (very religious). A regression analysis of data from 46 countries (n=46) yields the following model: Ŷ = 8.58 - 1.76x.
Canada has an HDI score of 0.94. The observed religiosity score for this country was 8.00. What is the residue of this country (round this number to 2 decimal places). And what does this number mean?
