To further elaborate the regression model, the researchers of the research project identified that the factors can be categorized as psychosocial and political-economic factors. The Psychosocial factors were the freedom, generosity, family and life expectancy while the political-economic factors were GDP per Capita and Government Corruption. To make sense of the factor distinctions, the researcher placed the psychosocial factors as predictors while the political-economic factors as mediators, thereby, implementing a mediation analysis. A. Which among the political-economic factors can be considered significant mediators between psychosocial factors and happiness? Provide parameter estimates and p-values. B. Using the Total-Indirect Effects table, which among the psychosocial factors (predictors) have significant indirect effects towards happiness? Provide parameter estimates and p-values. C. Describe why the mediators significantly mediate the relationships in 6A. Provide at least 2 research literature or articles per mediator. D. Based on your answer to 6B, why is the effect of the psychosocial factors of "indirect nature" towards happiness. Provide at least 2 research literature or articles per each predictor.
