Question

The accompanying scatterplot shows the growth rate (in % of Gross Domestic Product) of 27 countries from a certain region vs. the growth rate of the leading country in another region. Each point represents one of the years from 1970 to 2011. The output of a regression analysis follows the scatterplot. Complete parts a and b below. Click the icon to view the scatterplot and the output of the regression analysis. a) Check the assumptions and conditions for the linear model. What assumptions and conditions are met? O A. All of the assumptions and conditions are met. The variables are quantitative (with units % of GDP), the plot is reasonably straight, there are no outliers, and the spread is roughly constant (although the spread is large). OB. All of the assumptions and conditions are met with the exception of the Linearity Condition, the points do not follow a straight line pattern (as evidenced by the R2-value) O C. All of the assumptions and conditions are met with the exception of the Quantitative Variables Condition, the data are categorical. OD. All of the assumptions and conditions are met with the exception of the condition that there are no outliers (there is one outlier in the scatterplot).

Answer 1

A) option D is correct (since there is one outlier at the bottom of the curve,

O D. All of the assumptions and conditions are met with the exception of the condition that there are no outliers (there is one outlier in the scatterplot).

b)

option D is correct :about 44.97% of the variation in the growth rate of the countries,,,,,,,,,,,
