    Question

    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?


    1. TRUE: 1,07. The observed religiosity for Canada is 1.07 higher than the predicted score.
    2. FALSE: 1,07. The observed religiosity for Canada is 1.07 standard deviations higher than the mean score.
    3. FALSE: 6,93. The observed religiosity for Canada is 6.93 higher than the predicted score.
    4. FALSE: 6,93. The observed religiosity for Canada is 6.93 standard deviations higher than the mean score.

    1. True
    2. False
    3. False
    4. False
