Assignment Task:

INSTRUCTION

  • Please, answer in complete sentences.

  • Please, answer the questions in short paragraphs.

  • Please, write your R-code in the appendix of the same document

  • Please, round numbers to two digits after the decimal point

  • Please, add figure numbers and table numbers to your figures and tables

  • You may assume the methods you use (e.g. t-test, linear regression, etc.) are understood by the reader and do not need definitions, but you do need to explain the intuition of these methods

Questions

  1. Formulate hypotheses for both wealth variables and please write them out using the formal notation we have learned and justify the hypotheses.

  2. Create scatter plots for the relation between absolute wealth and happiness and relative wealth and happiness. Discuss the scatter plots.

  3. Regress life satisfaction on the Gini coefficient and GDP capita (life satisfaction is the dependent variable) as two separate bivariate linear regression models and present your results in a publication-style regression table.

  4. Interpret your models in statistical and in substantive terms. Also compare the models. Which fits the data better? How can you tell?

  5. Should we predict life satisfaction given a Gini coefficient of 85 based on our model? If so, what is the prediction? If not, why?

  6. Construct confidence intervals around the estimates of the coefficient for the Gini Coefficient and the coefficient for GDP/capita and interpret them.
