Question

the accompanying scatter plot shows growth (in % of Gross Domestic Product) of the developing countries vs the growth of developed countries for a particular region. Each point represent one of the years from 1964 to 2005. The output of a regression analysis follows the scatter plot. -Check the assumptions and conditions for the linear model. What assumptions and conditions are met?
A. All of the assumptions and conditions are met with the exception of the condition that there are no outliers (there are a total of three outliers in the scatter plot). B. All of the assumptions and conditions are met with the exception of the Quantitative Variables Conditions; the data are categorical. C. 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). D. 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). Scatterplot and Output of Regression Analysis 6- 5 Annual GDP Growth of Developed Countries (%) Dependent variable: GDP Growth Developing Countries R"= 19.19% s= 1.310 Variable Intercept GDP Growth Developed 0.460 Countries Coefficient 3.56

Explanation / Answer

C. 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).
