Predicting a nation's "average happiness" Consider five statistics for several nations: LSI, the average satisfaction score; GINI, the gini coefficient of income inequality (higher score = greater inequality); CORRUPT, the degree of corruption in government (higher score = less corruption); LIFE, the average life expectancy; and DEMOCRACY, a measure of civil and political liberties (higher score = more political liberties).Data on excel file happiness.xlsx

a.Using numerical and graphical summaries, describe the distribution of each variable.

b.Using numerical and graphical summaries, describe the relationship between each other.

c.Consider a model using GINI and LIFE. Run the MLR and summarize results. Be sure to check assumptions

d.Now consider a model using GINI, LIFE, and DEMOCRACY. Run the MLR and summarize the results. Again make sure to check assumptions.

e.Now consider a model using all four explanatory variables. Summarize results and check assumptions.
